Palpitations can feel like a racing, fluttering, pounding or skipped heartbeat. They are often linked to harmless triggers, but sometimes they signal an abnormal heart rhythm or another condition that needs attention. If you are asking, do I need to see a cardiologist for palpitations? The answer depends on how the episodes feel, how often they happen, your medical history and whether you have other symptoms. For more guidance on when symptoms merit specialist input, read our guide to when to see a cardiologist for heart palpitations.
Seek emergency help if palpitations come with chest pain, severe breathlessness, fainting or collapse. If episodes keep returning, last longer than usual, or concern you because of your health history, arrange a medical assessment. A GP can often be the right first contact and can refer you to a cardiologist when specialist investigation is appropriate. If you decide to seek an assessment, our guide explains what happens at a cardiology consultation.
What are heart palpitations?
Palpitations are the sensation that your heartbeat is unusually noticeable or different from normal. You may feel a thump, flutter, racing pulse, pause or a series of extra beats. The sensation itself does not identify the cause: similar feelings can occur with a normal rhythm as well as with an arrhythmia, which is an abnormal heart rhythm. You can also learn more about choosing the right cardiology test for your symptoms.
Common triggers include stress, anxiety, strenuous exercise, lack of sleep, caffeine, alcohol, nicotine, fever and some medicines. Palpitations can also be associated with medical issues such as an overactive thyroid, anaemia or a heart rhythm problem. It is not possible to tell which explanation applies from the sensation alone. If palpitations occur alongside chest discomfort, read our guide to chest pain assessment.
When should palpitations be assessed urgently?
Call 999 or seek emergency care if palpitations are happening now alongside chest pain or pressure, severe shortness of breath, fainting, collapse or severe dizziness. Do not drive yourself if you feel seriously unwell. If the symptoms have stopped but you experienced one of these warning signs, seek urgent medical advice.
Contact your GP or NHS 111 for prompt advice if symptoms are new, worsening or recurring and you are unsure how quickly you need to be seen. This is particularly important if you have a known heart condition or have previously been told you have an abnormal rhythm. If symptoms are severe, rapidly worsening or feel like an emergency, call 999 instead.
Do I need to see a cardiologist for palpitations?
A cardiology assessment may be useful when episodes are recurrent, unexplained, prolonged, or associated with other concerning symptoms. A clinician may also consider referral if you have a history of heart disease, an abnormal ECG, or a family history of sudden unexplained death or inherited heart conditions. These factors do not prove that a serious problem is present; they help guide how carefully symptoms should be investigated.
Many people can begin with their GP, who can review symptoms, medicines and general health, arrange initial checks and decide whether referral is needed. A cardiologist can assess possible heart-related causes and recommend further investigations or treatment if appropriate. If you are seeking private care, a cardiology consultation can provide a specialist assessment, but urgent symptoms still require emergency services rather than a routine appointment.
What will a cardiologist ask about?
The detail of an episode can help the clinician decide what to investigate. Be ready to describe:
- When the palpitations began, how often they happen and how long they last.
- Whether the heartbeat feels fast, irregular, forceful or as if it skips beats.
- What you were doing when an episode started and whether it stopped suddenly or gradually.
- Any chest discomfort, breathlessness, dizziness, fainting or reduced ability to exercise.
- Your medical conditions, family history, medicines and supplements, and use of caffeine, alcohol or nicotine.
Keeping a brief symptom diary can help, especially when episodes are intermittent. Note the time, duration, activity and any accompanying symptoms. Do not delay urgent care to collect more information.
Can a smartwatch diagnose the cause?
Wearables can be useful for recording the time of an episode and, on some devices, capturing a pulse or single-lead ECG tracing. Share relevant readings or recordings with a clinician if available. They may provide a useful clue, but they cannot reliably rule out every rhythm problem or replace a medical assessment and a clinical ECG.
A normal wearable reading between episodes does not necessarily explain what happened. Equally, an alert is not by itself a diagnosis. In October 2026, with more people using connected devices to track their health, the practical point remains the same: treat device information as supporting detail, not a substitute for care. Do not repeatedly check a device if it is increasing anxiety, and do not use it to decide against emergency help when warning symptoms occur.
What tests might be considered?
Testing is tailored to your symptoms and history; not everyone needs every test. A clinician may start with an examination and a standard ECG, which records the heart’s electrical activity for a short period. If symptoms come and go, a portable monitor worn for longer may be considered to try to capture an episode.
Depending on the findings, a cardiologist may discuss blood tests, an echocardiogram to assess heart structure and function, or an exercise test if symptoms are linked to exertion. The purpose is to look for a cause that would change your care, rather than to order tests simply because palpitations occurred.
What can you do while waiting for an appointment?
If you feel well and have no urgent warning signs, note your symptoms and review potential triggers. Consider whether episodes follow caffeine, alcohol, nicotine, poor sleep, stress or a new medicine. Do not stop prescribed medication without speaking to a healthcare professional. If an episode changes significantly, becomes persistent, or is joined by chest pain, severe breathlessness or fainting, seek urgent help rather than waiting for a planned appointment.
Dr. Chabok provides cardiology consultations, diagnostic assessment and treatment, including heart investigations and interventional procedures such as angioplasty and stenting. Clinics are listed in London and Harefield. The appropriate next step depends on your symptoms and clinical assessment; a consultation does not mean that an invasive procedure will be needed.
Frequently Asked Questions
Are palpitations always a sign of heart disease?
No. Palpitations can occur with everyday triggers or other health issues, and they do not always mean there is a heart problem. Recurrent, unexplained or concerning episodes should be discussed with a healthcare professional.
Should I see a cardiologist after one brief episode?
One brief episode without other symptoms may not require a cardiologist, but your circumstances matter. Speak with your GP if it recurs, worries you, or you have a heart condition or relevant family history. Seek emergency help for palpitations with chest pain, severe breathlessness, fainting or collapse.
Can an ECG be normal if palpitations come and go?
Yes. A standard ECG records only a short period, so it may not capture an intermittent episode. A clinician may consider a longer period of heart rhythm monitoring if your symptoms and history warrant it.
Should I stop caffeine or medication before an appointment?
Do not stop prescribed medication without medical advice. You can note your caffeine, alcohol and nicotine use and whether symptoms seem connected to them. A clinician can advise whether any changes are appropriate for you.
Can I book a private cardiology consultation for palpitations?
You can seek a private cardiology assessment for recurring or unexplained symptoms. If you have emergency warning signs, call 999 or seek emergency care rather than waiting for a private appointment.
