Palpitations are the awareness of your heartbeat: fast, forceful, or irregular. Most are benign (caffeine, poor sleep, stress, fever) — a few are the symptom of a rhythm disorder needing diagnosis. The distinction lives in the company they keep.
In short — what to do
- Sit, calm down, breathe slowly.
- If your doctor taught you a vagal manoeuvre (like forceful coughing or bearing down), use it — never improvise ones you weren't taught.
- Feel your pulse or record it (smartwatch/phone) — capturing the episode is a diagnostic treasure for your doctor.
- It stopped on its own and you feel fine? Book an appointment and bring your recording.

Your heart skipping or racing chaotically? The biggest mistake in that moment
23 secondsDon't self-diagnose online or settle for a cup of herbal tea. Rest and sit somewhere safe, don't drive, and get an ECG, the only test that names the rhythm problem. If dizziness, breathlessness, chest pain or fainting come with the palpitations: go to the ER at once.

Usually benign
- After caffeine, energy drinks, or smoking.
- With stress, sleep deprivation, or fever.
- Occasional "skipped" beats then normal rhythm — common in the healthy.
Worth assessment
- Episodes that start and stop abruptly like a switch, or extreme speed at rest.
- Totally irregular "quivering" palpitations — especially over sixty: may be atrial fibrillation, which raises stroke risk.
- Palpitations on exertion, or in anyone with known heart disease or a family history of early sudden death.
During an episode
- Sit, calm down, breathe slowly.
- If your doctor taught you a vagal manoeuvre (like forceful coughing or bearing down), use it — never improvise ones you weren't taught.

- Extreme speed continuing beyond 20–30 minutes without stopping.
One moment
The best gift you can give your doctor: a recording of the episode as it happens — a felt pulse, a smartwatch trace, a wrist ECG. Palpitation diagnosis lives on "catching it in the act".
