Skipped beats often are benign, while persistent symptoms may need evaluation

Arrhythmias fall into two categories: too fast or too slow. A racing heart or a skipped beat typically falls into the “too fast” category. In younger people, typically those in their 20s to 50s, the heart may suddenly speed up from a normal rate to 180–200 beats per minute. This rapid heartbeat can cause lightheadedness, dizziness, anxiety or, in some cases, fainting.
