Paroxysmal atrial fibrillation

During an episode, the upper chambers of the heart beat chaotically instead of following a steady rhythm. You may notice palpitations, breathlessness, tiredness, chest discomfort, or light-headedness, although some episodes cause no obvious symptoms. A normal pulse between episodes does not exclude the condition.

An ECG can record the rhythm, while a wearable or longer monitor may help capture an episode that comes and goes. The clinician may also review blood pressure, thyroid health, sleep, alcohol, medicines, and other heart conditions. Paroxysmal episodes can carry clot-related risk, so treatment decisions are individual.

Keep a record of when episodes begin, how long they last, your symptoms, and possible triggers. Take prescribed rhythm or rate medicines as instructed; never double a dose after a missed dose without advice. If anticoagulation management is prescribed, follow the schedule carefully and report unusual bleeding or a fall.

Attend follow-up even when episodes settle. Ask about an ECG, monitoring, sleep problems, blood pressure, and habits that may aggravate symptoms. Do not drive or operate machinery if you are dizzy or faint.

Call emergency services for chest pain, severe breathlessness, fainting, confusion, or a new one-sided weakness, facial droop, or speech difficulty. These symptoms may signal a serious heart problem or stroke. Seek prompt clinical advice for a new sustained episode, worsening symptoms, or repeated dizziness.

Ask how the rhythm was confirmed, whether you need an ECG monitor, and what your personal stroke-prevention plan is. Discuss rate control, rhythm control, medicine interactions, and the action to take if an episode starts at home.
