A fast heart rate can sometimes be normal (exercise, stress), but it can also signal a medical problem, so any sudden, very high, or persistent change deserves professional evaluation. If you feel chest pain, shortness of breath, fainting, or your heart is racing for no clear reason, seek urgent medical care instead of trying to fix it on your own.

Quick Scoop

  • Check if it’s an emergency
    • Call emergency services if you have chest pain, trouble breathing, feel like you might pass out, or your heart is suddenly pounding very fast at rest.
* Do not drive yourself if you feel faint or unstable.
  • Calm your body in the moment (for non‑emergency situations)
    • Sit or lie down, loosen tight clothing, and focus on slow, deep belly breathing: inhale through your nose for about 4 seconds, exhale slowly for 6–8 seconds, and repeat for a few minutes.
* Try gentle relaxation: keep your jaw, shoulders, and hands relaxed, and avoid holding your breath or tensing your muscles.
  • Breathing tricks that can help
    • Diaphragmatic (belly) breathing, box breathing (inhale 4 seconds, hold 4, exhale 4, hold 4), and similar paced-breathing methods have been shown to reduce heart rate and blood pressure in studies.
* Some people are taught “vagal maneuvers” (like a coached Valsalva maneuver or cold-water face immersion) to slow certain fast rhythms, but these should only be used under a clinician’s guidance because they are not safe for every heart condition.
  • Lifestyle steps that lower heart rate over time
    • Regular aerobic exercise, yoga, stress‑management practices, and good sleep can lower resting heart rate in the long run.
* Staying hydrated, limiting caffeine, nicotine, and excessive alcohol, and managing anxiety all reduce the chance of frequent high‑heart‑rate episodes.
  • When to talk to a doctor
    • If your resting heart rate is often above 100 beats per minute, drops unusually low, or feels irregular (skips, flutters), ask a healthcare professional for an evaluation.
* Share a log of when the fast heart rate occurs, what you were doing, any medications or stimulants used, and any symptoms like dizziness or chest discomfort.
