Recurring heart palpitations: what to know

Recurring heart palpitations deserve attention when they are new, changing, frequent, or occur with concerning symptoms. They may feel like racing, fluttering, pounding, skipped beats, or a brief thump in the chest. A prompt medical review can help identify the pattern and decide whether any testing is useful.

Palpitations describe your awareness of the heartbeat, rather than a diagnosis on their own. They can begin during stress, after caffeine or alcohol, with poor sleep, during fever, or after strenuous activity. Some episodes are related to medicines, supplements, nicotine, or recreational drugs. Changes in fluid intake, blood sugar, thyroid activity, or blood count can also be considered during an assessment.

The timing matters. A sudden rapid rhythm that starts and stops abruptly is different from an occasional isolated skip. Noting whether episodes happen at rest, with exertion, after meals, or when lying down gives a clinician useful clues.

Keep a simple episode record: when it started, how long it lasted, what you were doing, the sensation, and any symptoms such as breathlessness, dizziness, chest discomfort, sweating, or nausea. If you can safely check your pulse, note whether it seems fast, slow, steady, or irregular. Bring a list of prescribed medicines, over-the-counter products, supplements, and stimulants.

Until you are assessed, avoid obvious personal triggers where practical and make regular meals, hydration, rest, and stress management part of your routine. Do not stop prescribed heart or other medicines without medical advice. A clinician may check your pulse and blood pressure, arrange a heart tracing, or use other tests based on your symptoms and history.

Seek emergency help now if palpitations come with chest pain or pressure, fainting, severe shortness of breath, new confusion, or a feeling that you may pass out. These symptoms need urgent assessment even if the heartbeat settles. Arrange a timely medical appointment for recurrent episodes, an irregular pulse, symptoms during exercise, or palpitations that are becoming more noticeable.

Ask what rhythm problem, if any, is being considered; whether your medicines or supplements could contribute; which symptoms should prompt emergency care; and whether a heart tracing or rhythm monitor would be appropriate. Tell them about any family history of rhythm problems or sudden unexplained death, and about recent illness, pregnancy, or major changes in exercise.
