Cardiac arrhythmia

Overview

Cardiac arrhythmia is an irregular heartbeat. The heart may beat too fast, too slow or in an erratic way. It happens when electrical signals in the heart don't work as they should.

Symptoms

There may be no symptoms. Or they may include a fluttering, pounding or racing feeling in the chest, chest pain, shortness of breath, and dizziness.

Treatments

Some cardiac arrhythmias do not need treatment. Treatment, if needed, may include medicines, specific actions such as coughing, implanted devices, or a procedure or surgery.
