A flutter, thump or sudden racing heartbeat can be unsettling. If you are asking, do I need to see a cardiologist for palpitations? the answer depends on the pattern, any other symptoms and your medical history. Many palpitations are not caused by a serious heart problem, but a new, persistent or concerning change should be assessed. You can also read our guide on when to see a cardiologist for heart palpitations.
A useful way to think about palpitations is to look beyond a single pulse reading. When they happen, how they start and stop, what you feel alongside them, and whether they recur can help a clinician decide what investigation is appropriate. A smartwatch recording may offer a clue, but it cannot confirm or rule out a heart rhythm condition on its own. If you are considering an appointment, learn more about what happens at a cardiology consultation.
What are heart palpitations?
Palpitations are sensations that make you unusually aware of your heartbeat. People describe a heart that is racing, pounding, fluttering, skipping beats or giving an extra thump. The sensation may last for a few seconds or continue for longer, and it may occur at rest or during activity. Our guide to choosing the right cardiology test explains how investigations can help assess symptoms.
Palpitations are a symptom, not a diagnosis. They can occur with stress, poor sleep, caffeine, alcohol, some medicines or a fever. Sometimes they are linked to a change in heart rhythm, such as an irregular rhythm. A clinician needs to consider the whole picture rather than assume the cause from how the sensation feels.
When should I seek emergency help?
Call 999 in the UK if palpitations are happening with chest pain or pressure, severe shortness of breath, fainting, collapse or feeling as though you may lose consciousness. Do not drive yourself to hospital if you may be seriously unwell.
If the episode has stopped but you experienced fainting, significant chest discomfort or severe breathlessness, seek urgent medical advice. For symptoms that are new, worsening or troubling but not immediately life-threatening, contact your GP or NHS 111 for advice about how quickly you should be assessed. A private cardiology appointment is not a substitute for emergency care.
When is a cardiology assessment worth considering?
Arrange medical advice if palpitations keep returning, last longer than usual, are becoming more frequent, or affect your ability to exercise or carry out normal activities. A GP may be a good first point of contact. A cardiologist may be appropriate if a heart rhythm problem is suspected, symptoms remain unexplained, an initial assessment suggests a heart condition, or specialist investigation is needed.
It is particularly important to mention palpitations that occur during exertion or alongside dizziness, unusual breathlessness or chest discomfort. Also tell the clinician if you have a known heart condition, have previously had an abnormal heart test, or have a close family history of a serious heart rhythm problem or sudden cardiac death at a young age. These details do not automatically mean you have a serious condition, but they can affect the assessment.
What details can help identify a pattern?
For a fresh and useful view of palpitations, focus on the sequence of events rather than just how fast your pulse seemed. If it is safe to do so, make a brief note of:
- When the episode started and how long it lasted.
- Whether the heartbeat felt regular, irregular, fast or like occasional skipped beats.
- What you were doing at the time, including exercise, rest or a stressful moment.
- Any symptoms such as dizziness, chest discomfort, breathlessness or faintness.
- Potential triggers, recent illness, and medicines or supplements you take.
A watch or phone may record a pulse or, on some devices, an ECG-style trace. Save the recording and note the time if you have one, but do not rely on it to decide that you are safe or to diagnose yourself. A device reading can be incomplete or misleading, and a normal reading between episodes does not necessarily explain symptoms that come and go.
What might happen during a cardiology assessment?
A cardiologist will usually ask about your symptoms, medical history, family history and medicines, and may examine you. The next steps depend on what the history and examination suggest. An electrocardiogram (ECG) records the heart’s electrical activity during the test. If symptoms are intermittent, a wearable heart monitor may be used for a longer period to try to capture an episode.
An echocardiogram uses ultrasound to assess the heart’s structure and pumping function. Blood tests may be considered to check for possible contributing factors, depending on your symptoms and history. Not everyone needs every test. A normal ECG at one appointment can be reassuring, but it may not capture an intermittent rhythm issue; your clinician can decide whether further monitoring is appropriate.
Preparing for an appointment
Bring a list of medicines and supplements, any relevant previous test results, and your notes or device recordings. Be ready to describe what the sensation feels like and whether it begins and ends suddenly or gradually. If you have noticed a connection with exercise, caffeine, alcohol, illness or a new medicine, mention it. Do not stop prescribed medication without advice from the clinician who manages it.
Dr Chabok provides cardiology consultations, diagnosis and treatment, with clinics listed in London and Harefield. A consultation can help determine whether further heart investigations or treatment are appropriate for your individual circumstances.
Frequently Asked Questions
Are palpitations always a sign of a heart problem?
No. Palpitations can have several causes, including everyday triggers, and do not always indicate heart disease. Recurrent, persistent or concerning symptoms should still be discussed with a healthcare professional.
Should I see a cardiologist if my ECG is normal?
Not necessarily, but a normal ECG records the heart during a particular period and may not capture symptoms that happen intermittently. If palpitations continue or you have other concerning symptoms, ask your GP or cardiologist whether monitoring or another assessment is appropriate.
Can a smartwatch diagnose the cause of palpitations?
No. A device recording can be useful information to share with a clinician, but it is not a substitute for medical assessment and may not provide a complete or reliable diagnosis.
What symptoms with palpitations need emergency help?
Call 999 for palpitations accompanied by chest pain or pressure, severe shortness of breath, fainting or collapse. Seek urgent advice if you feel seriously unwell.
Should I see my GP or book a cardiologist first?
For non-emergency symptoms, your GP can review your history and advise on initial checks or referral. You may also seek a private cardiology consultation if you want specialist assessment. Choose emergency services instead if you have urgent warning symptoms.
