What to do if…
you notice a new irregular heartbeat or skipped beats and feel unsettled

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

If the irregular heartbeat comes with chest pain, shortness of breath, fainting, near-fainting, dizziness, lightheadedness, unusual sweating, or you feel seriously unwell, call 911. If there are no emergency symptoms but this is new, different, or keeps happening, get same-day medical guidance.

Do not do these things

  • Do not drive yourself to care if you feel faint, very dizzy, confused, weak, or unsteady.
  • Do not do intense exercise to “test” your heart while the rhythm feels off.
  • Do not take extra prescribed medicine, someone else’s medicine, or supplements to slow your heart unless a clinician tells you to.
  • Do not stack stimulants such as energy drinks, high caffeine, nicotine, recreational stimulants, or stimulant decongestants.
  • Do not repeatedly check your pulse in a way that makes panic build.

What to do now

  1. Sit down somewhere safe. Put both feet on the floor and take a few slow breaths so you can check what is happening without rushing.

  2. Call 911 now if the irregular heartbeat or skipped beats come with any of these:

    • chest pain, pressure, or tightness
    • shortness of breath or trouble breathing
    • fainting, near-fainting, collapse, or loss of alertness
    • dizziness, lightheadedness, confusion, or feeling too weak to stand safely
    • unusual sweating, nausea, or a strong feeling that something is seriously wrong

  3. If there are no emergency symptoms, contact a medical service for same-day guidance. Call your doctor’s office, nurse line, urgent care, or a local ER and say: “I have a new irregular heartbeat or skipped beats, and I need advice on where to be seen.”

  4. Make a brief episode note before details fade. Write down:

    • when it started and how long it lasted
    • whether it felt like fluttering, skipping, pounding, racing, or pauses
    • what you were doing right before it started
    • any recent caffeine, energy drinks, alcohol, nicotine, decongestants, new medicines, new supplements, recreational stimulants, dehydration, poor sleep, fever, or illness
    • any known heart condition or family history of serious rhythm problems, if you know it

  5. If checking your pulse helps, keep it brief. Use your wrist or a wearable if you already have one; note whether it feels very fast, very slow, regular, or irregular, then stop checking and follow the care plan.

  6. Reduce strain while you arrange care. Rest, avoid caffeine, nicotine, alcohol, stimulant decongestants, and intense exercise for now, and sip water if you may be dehydrated unless you have been told to restrict fluids.

  7. Ask another person to stay nearby or be reachable if you feel shaky, lightheaded, or scared. If symptoms worsen while you are waiting for advice, call 911.

  8. If you already have a wearable rhythm recording, save it. Do not delay emergency care or same-day medical guidance to capture a recording.

What can wait

  • You do not need to decide the cause right now.
  • You do not need to research every possible diagnosis.
  • You do not need to start, stop, or change medication on your own.
  • You do not need to decide now whether this is stress, caffeine, anxiety, or an arrhythmia.

Important reassurance

Palpitations and skipped beats can feel intense and frightening. The immediate job is to spot emergency symptoms, reduce avoidable strain, and get the right level of medical advice without trying to diagnose yourself.

Scope note

This guide covers first steps only. Later decisions, such as an ECG, rhythm monitor, blood tests, medication changes, or specialist review, may need help from a clinician.

Important note

This is general information only, not medical advice, a diagnosis, or a substitute for professional care. If you feel seriously unwell, symptoms worsen, or you are unsure whether it is an emergency, call 911 or go to an ER.
