What are ectopic heartbeats and why do they happen?
00:33
Summary
Ectopic heartbeats are very common and often cause noticeable palpitations. In this video, Dr Ravi Assomull describes why these extra beats occur and why they are usually harmless.
Transcript
Ectopic beats are extra beats that arise from outside the normal pacemaker of the heart. They are very common and in the vast majority of cases are entirely harmless. The symptoms of an ectopic beat include those of a skipped beat, a flutter, a thudding or the sensation of a dropped beat. These sensations typically occur because what happens is there is a short pause after an ectopic beat, which is then followed by a stronger heartbeat.
Dr Ravi Assomull
What triggers ectopic heartbeats and how can they be reduced?
00:55
Summary
Certain lifestyle and medical factors can increase the frequency of ectopic heartbeats. In this video, Dr Ravi Assomull, a Private Cardiologist in London, explains common triggers and how symptoms can be reduced.
Transcript
You're more likely to get ectopic beats due to certain triggers and these typical triggers include a lack of sleep, anxiety, stress, also consumption of excess caffeine or alcohol are very well documented triggers. In more recent times we've become aware of viral infections causing ectopic beats. Certainly during the COVID pandemic one of the key cardiac symptoms associated with a COVID infection were palpitations due to ectopic beats. Finally with hormonal changes such as those experienced during the menopause or pregnancy ectopic beats can be more prevalent and using certain drugs such as nasal decongestants or stimulants can also trigger these ectopic beats.
Dr Ravi Assomull
Are ectopic heartbeats dangerous and when should they be checked?
00:39
Summary
Many people experience ectopic heartbeats, but knowing when to investigate them is important. In this video, Dr Ravi Assomull explains when ectopics are harmless and when ECGs and further tests are required.
Transcript
In the vast majority of patients, ectopic beats are not dangerous at all. We have to make this judgment by performing an assessment. This will include ensuring that you have a normal ECG, a normal echocardiogram, and by that we are looking to ensure that your heart is structurally normal. Critically, we also need to ensure there is no family history of any premature cardiac death, and specifically exclude any family history of sudden cardiac death. Finally, we also need to make sure you have no red flag symptoms such as loss of consciousness.

How are ectopic heartbeats diagnosed and monitored?
00:39
Summary
The diagnosis of ectopic heartbeats relies on correlating symptoms with heart rhythm recordings. In this video, Dr Ravi Assomull, a Private Cardiologist in London, explains how ECG monitors are used to assess ectopic beats.
Transcript
The diagnosis of ectopic beats are often made just by taking the history alone. But to prove that in fact these are ectopic beats and critically to assess whether there are any associated heart rhythm disturbances, the key test is one of an ECG monitor. This involves popping a patch on your chest which records your heart rhythm for anywhere between one day and 14 days. And what we're looking for here is correlation between your symptoms and the heart rhythm that's recorded on the ECG monitor.
Dr Ravi Assomull
How are ectopic heartbeats treated and when is treatment needed?
00:49
Summary
Treatment options for ectopic heartbeats are discussed, from lifestyle changes to medication and catheter ablation. In this video, Dr Ravi Assomull explains when reassurance alone is sufficient.
Transcript
In the vast majority of cases we can simply reassure you that there is nothing to worry about here. Simple lifestyle modification can help greatly. By this I mean reducing your caffeine and alcohol consumption, prioritising sleep, trying to ameliorate stress and anxiety, or stopping certain medications that are perhaps provoking these symptoms. If lifestyle modification doesn't work then we can use medications such as beta blockers which will suppress these ectopic beats. They don't cure it but certainly make you feel better. In a minority of cases where the ectopic burden is very high and the symptoms are very intrusive we can actually perform a procedure called a catheter ablation which should get on top of the problem.
Dr Ravi Assomull
Is it safe to exercise if you have ectopic heartbeats?
00:22
Summary
Exercise is often safe for people experiencing ectopic heartbeats. In this video, Dr Ravi Assomull describes when physical activity is encouraged and when symptoms should prompt further assessment.
Transcript
Exercise tends to be very safe and actually in most people the ectopics completely disappear with exercise. We would advise against exercise if your ectopics are worse when you exercise or if you have other symptoms such as dizziness, loss of consciousness or chest pain.

What is the difference between atrial and ventricular ectopic beats?
00:43
Summary
The differences between atrial and ventricular ectopic beats are clearly outlined. In this video, Dr Ravi Assomull describes how ectopic burden is assessed and why most ectopic beats are considered benign.
Transcript
There are two types of ectopic beats, those that arise from the upper chambers of the heart. We refer to these as atrial ectopic beats. These are entirely harmless and you can have as many as 20 to 30 percent of your heart beat being ectopic atrial beats without us having any concerns. You can also have ectopic beats that arise from the left ventricle. Whilst these also tend to be entirely benign, we tolerate a lower burden of ventricle ectopic beats. Certainly when you have ectopic beats that exceed 1 percent of your total heartbeat, we like to make sure that you have a structurally normal heart by performing an echocardiogram.
Dr Ravi Assomull
What is ectopic burden and when is it considered normal?
00:18
Summary
The concept of ectopic burden and how it is measured over a 24 hour period is explained. In this video, Dr Ravi Assomull explains why a low ectopic burden is usually considered normal and reassuring.
Transcript
An ectopic burden refers to the percentage of ectopic beats over a 24-hour period. An ectopic burden of 1% is considered low and is labelled as being entirely benign.
Dr Ravi Assomull
What is arrhythmia?
00:38
Summary
What exactly is an arrhythmia? Not all abnormal heart rhythms are dangerous. In this short video, Dr Ravi Assomull clarifies the difference between benign arrhythmias (like ectopic beats) and more serious conditions like atrial fibrillation (AF), which increases stroke risk. If you’ve experienced palpitations or irregular heartbeats, it’s essential to seek expert guidance. Dr Assomull specialises in personalised arrhythmia assessment and management using advanced diagnostics and imaging.
Transcript
Arrhythmia is an abnormal heart rhythm. If you have an arrhythmia, it doesn't necessarily mean there is anything to worry about. A lot of arrhythmias are what we refer to as benign. Typically, these are ectopic, extra heartbeats, they tend to be short-lived and pose no risk to you. There are more concerning arrhythmias such as atrial fibrillation, which is the most common heart rhythm disturbance in this country. The key concern with atrial fibrillation is that, as well as causing symptoms, it is associated with an increased risk of stroke.
Dr Ravi Assomull
Can arrhythmia be treated and cured?
01:07
Summary
Can arrhythmias be permanently cured, or only controlled? In this video, Dr Ravi Assomull, expert Consultant Cardiologist in London, explains that arrhythmias are common and often benign heart rhythm disturbances. Treatment depends on identifying the exact rhythm problem and may include lifestyle changes, medication or in a small number of cases procedures such as cardioversion or ablation. Diagnosis is usually made with a wearable ECG monitor worn for up to 14 days during normal daily life. Recording symptoms like palpitations allows accurate correlation with heart rhythm, helping guide personalised and effective arrhythmia management.
Transcript
Arrhythmias can typically be treated using a combination of lifestyle modification, medications and in a minority of cases a procedure such as an ablation or a cardioversion may be required. Very few arrhythmias can actually be cured as such. It's highly likely once you've had an arrhythmia you'll get a recurrence. But bearing in mind most arrhythmias are benign, these aren't of any clinical concern and should pose no risk to you in the future. The key to formulating a treatment for your arrhythmia is actually identifying what the underlying arrhythmia is. This is done by getting an ECG monitor which we can stick on your chest for up to 14 days and asking you to live your life as usual. When you have the symptoms that represent your possible arrhythmias such as palpitations it's key that you record the time and date and we can then see what we found on the heart rhythm monitor. That heart rhythm symptom correlation is critical in identifying what your arrhythmia is and figuring out whether you need just advice on your lifestyle, medications or a combination of both.
What is an ectopic heartbeat?
An ectopic heartbeat is a beat that starts somewhere other than the heart’s natural pacemaker, known as the sinoatrial (SA) node. In a normal heartbeat, an electrical impulse travels from the SA node, through the upper chambers of the heart (the atria), and down into the lower chambers (the ventricles), causing a coordinated, rhythmic contraction.
With an ectopic beat, an impulse starts early from somewhere else in the heart, before the next normal beat is due. This causes the heart to beat slightly earlier than expected, out of its normal sequence, followed by a brief pause while the normal rhythm resets.
This pause and the beat that follows it can cause the feeling of a skipped heartbeat, a thud, or a flutter. This can be unsettling, particularly the first time it occurs.
Ectopic heartbeats are very common. The majority cause no harm and do not require treatment, but they do need a proper medical assessment to understand what is driving them and whether they are caused by an underlying condition that may need medical attention.
Types of ectopic heartbeats
Ectopic beats are named according to where in the heart they originate. There are two main types: Ventricular ectopics and supraventricular ectopics (SVEs).
Ventricular ectopics
Ventricular ectopics (VEs), also called premature ventricular contractions (PVCs), are very common. They originate in the heart’s lower chambers, known as the ventricles. This electrical impulse travels through the ventricles in an abnormal direction, resulting in a less coordinated heartbeat than usual.
Ventricular ectopics are often harmless in the context of a structurally normal heart, but when they are very frequent or associated with an underlying heart condition, they may require closer attention.
Supraventricular ectopics
Supraventricular ectopics (SVEs), also known as premature atrial contractions (PACs), originate in the upper chambers of the heart (the atria) or in the tissue between the atria and ventricles. They are also very common and are usually benign. They can feel similar to ventricular ectopics but are typically less symptomatic. In a small number of cases, frequent SVEs can be associated with a higher risk of atrial fibrillation.
Symptoms
Many people with ectopic heartbeats have no symptoms at all and the extra beats are found on an ECG during a routine assessment. For others, the sensations can feel concerning, even when the ectopic beats are benign.
Common symptoms can include:
- A skipped beat that can feel like a brief pause followed by a more forceful beat
- A thud in the chest, as the beat that follows the ectopic pause, can feel stronger
- A fluttering sensation in the chest or throat
- An awareness of an irregular or erratic pulse
- Brief dizziness or light-headedness
- Fatigue, particularly when ectopics are frequent
- Shortness of breath
Symptoms are often more noticeable at rest, particularly in the evenings or at night when the heart rate naturally slows. Many people find their symptoms disappear when they exercise and return when they stop.
The sensations can feel worse with alcohol, caffeine, fatigue, stress or poor sleep. These lifestyle factors are also relevant to your broader cardiovascular health and are addressed directly as part of our integrative cardiology approach.
If you experience ectopic beats accompanied by sudden chest pain, shortness of breath, fainting, loss of consciousness, or a very fast or irregular heartbeat that does not settle, call 999 immediately for emergency medical attention.
Causes
Ectopic heartbeats can occur in a completely healthy heart with no identifiable cause. They can also be triggered or worsened by a range of factors, many of which are within your control.
Common triggers can include caffeine, alcohol, fatigue, poor sleep, stress, strenuous exercise, certain medications and supplements such as nasal decongestants, electrolyte imbalances, viral infections, hormonal changes, thyroid disorders or smoking nicotine.
In a minority of patients, ectopic beats may be associated with an underlying structural or electrical heart condition. This is why a proper assessment, including cardiac imaging, is important even when ectopic beats are suspected to be benign. Potential cardiac causes can include:
- Structural heart disease including heart failure or cardiomyopathy
- High blood pressure, which over time can cause changes to the heart muscle and lead to arrhythmia
- Scarring from a previous heart attack, which can create new focus points for ectopic electrical activity
- Myocarditis, which is inflammation of the heart muscle
- High ectopic burden when ectopics make up more than 10-15% of all heartbeats, which may affect cardiac function over time
The key distinction is identifying ectopics in a structurally normal heart and those associated with underlying heart disease. This can be established with a thorough medical history, examination, investigations and diagnosis.
Diagnosis
Diagnosing ectopic heartbeats and understanding their significance requires a careful clinical assessment with targeted investigations. This will help determine what is causing them, how frequent they are, and whether there is an underlying condition that may require treatment.
During your initial appointment, we will take a detailed medical history to assess your symptoms, triggers, lifestyle and family history. This may also involve a physical examination to get a better understanding of your heart health.
Some initial tests we may perform can include a resting electrocardiogram (ECG) to record the heart’s electrical activity and an echocardiogram to assess the structure and function of the heart.
We may also recommend an ambulatory ECG monitor to be worn at home for 24 hours or longer to capture your heart’s activity during daily tasks. This allows us to identify how many ectopic beats you have, their patterns and any other arrhythmias.
You may need blood tests, such as thyroid function, electrolytes (potassium and magnesium), and inflammatory markers, to help identify any underlying cause.
In selected patients, an exercise ECG can provide important additional information about how the heart rhythm changes under exertion.
We may suggest further investigations depending on your individual situation, symptoms and history. At Cardiologist London, we are here to support you through every step of your journey.
Treatment
For many patients, an important part of managing ectopic beats is knowing what to expect.
We will discuss the treatment options with you based on your personal circumstances, condition and needs. This may include lifestyle changes, monitoring and, occasionally, medication.
Reassurance and monitoring
If your investigations confirm a structurally normal heart and a low ectopic burden, you may not require treatment. Knowing that the sensations you are experiencing are not dangerous and understanding their cause can help reduce your anxiety and concern. We will explain your results in full detail and discuss a clear plan with you for any follow-up or monitoring that may be needed.
Lifestyle modification
Addressing lifestyle factors is a key part of managing ectopic heartbeats. Many patients experience a meaningful reduction in the frequency and severity once they address their triggers. This may include:
- Reducing or eliminating caffeine: This is one of the most common and impactful changes for patients with lifestyle-triggered ectopics.
- Reducing alcohol: This can significantly lower ectopic beat frequency.
- Improving sleep: Addressing sleep disruption can reduce sympathetic nervous system activity and support cardiovascular health.
- Managing stress: Evidence-based approaches such as mindfulness, structured movement and psychological support can help you manage your stress levels.
- Regular exercise: This can help reduce ectopic frequency over time.
- Maintaining a healthy, well-balanced diet: This can support electrolyte optimisation and cardiac electrical stability.
At Cardiologist London, our personalised integrative cardiology approach can help you make meaningful changes to your lifestyle to improve your condition and your overall cardiovascular health.
Medication
When lifestyle changes alone are not enough, we may recommend medication. This can include:
- Beta-blockers to help improve symptoms and control the area of the heart sending out the extra heartbeats.
- Calcium channel blockers, if beta-blockers are not tolerated well.
- Anti-arrhythmic medication for a small number of patients with very frequent or distressing ectopics that have not responded to other treatments.
Catheter ablation
For a few patients, typically those with a high ventricular ectopic burden that is affecting their heart function or those with very frequent ectopics that are unresponsive to treatment, catheter ablation may be considered. This minimally invasive procedure targets and eliminates the specific focus in the heart that is causing the extra beats.
Ectopic beats and excercise
The relationship between ectopic heartbeats and excerise is a common uncertainty for patients, particularly for athletes and those who exercise regularly.
For most patients, moderate aerobic exercise can be both safe and beneficial. Regular exercise can reduce the sympathetic nervous system activity, improve sleep quality, reduce stress and may reduce ectopic frequency over time.
There is a specific subgroup of patients, however, who have exercise-induced ectopics. This is a pattern where ectopic beats become more frequent or symptomatic during physical activity. This is different from ectopics that are reduced by exercise and may require targeted assessments, including an exercise ECG.
For athletes with frequent ectopics, questions around returning to sport and competitive exercise are taken seriously and addressed with objective investigations. At Cardiologist London, our aim is to reach a clear, evidence-based, individualised plan about what is safe and appropriate for you and your needs.
Our integrative cardiology approach
Understanding ectopic heartbeats, the triggers and what to expect can make a significant difference to your experience.
At Cardiologist London, we take the time to understand your cardiovascular health holistically and we look beyond the electrical findings to address the lifestyle factors that may be driving your condition. Addressing these factors properly will not only help reduce your ectopic burden, but it will also optimise your heart health for the future.
Recommended tests for Ectopic heartbeats

Electrocardiogram (ECG or EKG)
An electrocardiogram is a test that measures and records your heart’s electrical activity and rhythm, including the strength and speed of your heartbeat.

Ambulatory ECG monitor
Ambulatory electrocardiogram (ECG) monitors are devices that help take readings of your heart’s electrical activity during your daily activities over a longer period of time.

Echocardiogram
An echocardiogram is an ultrasound scan that shows the heart’s structure and surrounding blood vessels. It allows us to analyse how blood flows through them and assess the heart’s pumping chambers.
