Also known as: Tachycardia
A rapid heartbeat is a heart rate exceeding 100 beats per minute at rest. It can feel like the heart is racing, pounding, or fluttering and may be caused by exertion, anxiety, or cardiac conditions.
Tachycardia is defined as a resting heart rate over 100 beats per minute. While often benign and related to exercise, caffeine, or anxiety, it can also indicate cardiac arrhythmias requiring treatment.
Sinus tachycardia (normal heart rhythm, just faster) is the most common type and usually has an identifiable trigger. Supraventricular tachycardia (SVT) and atrial fibrillation are abnormal rhythms that may need medical intervention.
Hyperthyroidism, anemia, and dehydration are important systemic causes that produce rapid heartbeat as a compensatory response.
There are several possible reasons you may be experiencing Rapid Heartbeat. Here are the most common ones.
Sympathetic nervous system activation increases heart rate as part of the fight-or-flight response.
Caffeine, nicotine, and decongestants stimulate the heart and increase rate.
Reduced blood volume causes the heart to beat faster to maintain blood pressure.
Chaotic electrical signals in the atria cause rapid, irregular heartbeat requiring treatment.
These approaches may help manage rapid heartbeat at home. Always consult a healthcare provider if symptoms persist or worsen.
Bearing down, cold water on the face, or coughing stimulate the vagus nerve to slow heart rate.
Slow, controlled breathing activates the parasympathetic nervous system.
Cutting back on coffee, tea, and energy drinks can significantly reduce episodes.
ECG to capture the rhythm, Holter monitor for intermittent episodes, echocardiogram, thyroid function tests, and blood count.
Seek emergency care if rapid heartbeat is accompanied by chest pain, fainting, severe shortness of breath, or lasts more than a few minutes at rest.
Steps you can take to reduce the likelihood of experiencing rapid heartbeat.
Limit caffeine and stimulants
Stay hydrated
Manage stress and anxiety
Regular moderate exercise
Sustained resting heart rate over 150, or any rapid rate with chest pain, fainting, or severe breathlessness needs emergency care.
Yes. Anxiety commonly raises resting heart rate to 100-120+ bpm through adrenaline release.
Brief episodes from exertion or stress are usually harmless. Chronic or very rapid tachycardia can strain the heart over time.
