An erratic heart rate is caused by the heart pumping blood too slowly or too quickly throughout the body.

The average heart rate, or your pulse, in adults should be between 60 beats per minute (bpm) and 100 bpm when you are at rest. An erratic pulse is an abnormally low or high heart rate compared to this average.

    Frequently asked questions

    Short answers from Dr Ravi Assomull, consultant cardiologist - each one is also available as a video.

    What are irregular heart beats?

    Irregular heartbeats occur when your heart does not maintain its usual steady rhythm. Instead of beating consistently at 60 to 80 beats per minute, it may vary significantly, sometimes slowing or speeding up. This variation can feel like fluttering or skipping and often needs further investigation to determine the underlying cause. In this video, Consultant Cardiologist Dr Ravi Assomull explains what may be behind these changes and when to seek medical advice. Watch Dr Assomull's answer (0:50).

    What is the difference between palpitations and an irregular heart beat?

    Palpitations are sensations you feel in your chest, such as fluttering or skipped beats, while an irregular heartbeat refers to a confirmed variation in your heart’s rhythm. An irregular heartbeat is often linked to conditions like atrial fibrillation. In this video, Dr Ravi Assomull explores how palpitations and irregular rhythms are connected, what causes them, and when they may indicate a more serious heart issue.

    What can cause irregular heart beats?

    Atrial fibrillation is the most common cause of abnormal heart rhythm and affects over 1.5 million people in the UK. It can significantly raise your risk of stroke, making early diagnosis essential. In this video, Dr Ravi Assomull explains how atrial fibrillation affects the heart, and how starting the right treatment can reduce your risk of complications. Watch Dr Assomull's answer (0:40).
