Atrial Flutter

Symptoms

Some people may experience no symptoms, and the atrial flutter is identified accidentally during a routine electrocardiogram.

In others, the atrial flutter may be chronic (occurring repeatedly or constantly) or in episodes, with occasional attacks that last hours or days, followed by periods of normal heart rhythm.

Symptoms of atrial flutter, which may begin or stop suddenly, include:

• Rapid, racing or irregular (heart palpitations) heartbeat
• Shortness of breath and breathing difficulty
• Chest tightness
• Fatigue
• Dizziness and light-headedness
• Fainting
• Confusion
