Atrial flutter

Overview

Rapid contractions of the upper chambers of the heart may spread to the lower chambers, resulting in rapid heartbeats.

Symptoms

Symptoms may include a racing heart (palpitations), shortness of breath, chest pain, and dizziness.

Treatments

Medications, electric shock, or procedures that destroy abnormal tissue in the heart may be used to restore a normal heartbeat or control the rate or prevent blood clots.
