About this symptom
Palpitations are the sensation of a fast, strong or uneven heartbeat, sometimes described as a skipped beat. Stress, caffeine, poor sleep, anaemia, hormonal changes and heart arrhythmias can all be associated with these sensations. Similar symptoms can have different causes.
What to record about an episode
Note when it starts, how long it lasts, whether the pulse seems regular and whether exertion, drinks or medication are involved. If episodes recur, record their frequency and associated dizziness, chest pain, weakness or breathlessness.
When to arrange a cardiology visit
Seek assessment if episodes recur, become longer or more intense, or develop alongside known heart disease. Describe symptoms even if they have stopped: a short ECG may not capture a past episode.
What not to do without medical advice
Do not start antiarrhythmic drugs or stop prescribed treatment on your own. Readings from a watch or fitness tracker can provide extra context but cannot replace diagnostic testing.
Signs and symptoms
A fluttering, pounding or racing heartbeat can be accompanied by anxiety, weakness or dizziness. Loss of consciousness, severe breathlessness or intense chest pain are dangerous associated symptoms.
Diagnosis and tests
A cardiologist reviews symptoms, pulse, blood pressure and risk factors. An ECG, 24-hour or longer heart rhythm monitoring, blood tests or other investigations may be appropriate.
The assessment depends on how often episodes occur and how severe they are.
Care and treatment approaches
If a cause is identified, the clinician can recommend treatment or follow-up. Managing triggers may help some people but does not replace assessment of a possible arrhythmia.
When to seek urgent care
Call 103 in Ukraine immediately if palpitations come with fainting, chest pain, marked breathlessness or a sudden serious deterioration.
Frequently asked questions
Does a strong heartbeat always mean an arrhythmia?
No. Heartbeat sensations have many potential causes, so recurring episodes merit assessment.
Why might an ECG monitor be worn for a day or longer?
A brief ECG may miss an occasional episode. Longer monitoring can help link symptoms to the recorded rhythm.
