Rapid Heartbeat — Which Doctor Should I See?

A rapid heartbeat, or tachycardia, occurs when your heart beats faster than normal, typically over 100 beats per minute at rest. It can feel like pounding, fluttering, or racing in your chest.

Common causes include anxiety, stress, caffeine, exercise, fever, hyperthyroidism, anemia, and certain medications. Some causes are harmless, while others require medical attention.

Seek medical care if rapid heartbeat persists, is accompanied by chest pain, shortness of breath, dizziness, or fainting. Also consult a doctor if episodes occur frequently without obvious triggers.
