Heart Palpitations
Human Heart I Stock 000016015562 Medium

Stress, anxiety and caffeine are major contributors to a rapid heartbeat — and caffeine can surprisingly be found in everything from soda to certain medications, to weight loss pills and energy drinks.

A normal radial pulse (taken via the wrist) should be between 60 to 100 beats per minute, and slightly higher if taken while in the midst of activity. Heart palpitations are serious when the heartbeat is irregular and are a cause for concern. Possible serious reasons for an irregular heartbeat that require a visit to the doctor may be atrial flutter, atrial fibrillation, ventricular tachycardi or other arrhythmias.

ER physician Dr. Travis Stork shows the anatomy of an increased heart beat.
