What are Arrhythmias

Arrhythmias are abnormal beats of the heart. An arrhythmia can be caused by the heart's natural pacemaker developing an abnormal rate. Some arrhythmias may occur without any symptoms. Others may cause noticeable symptoms, such as fainting, dizziness or chest pain.

Treatment for arrhythmias may include medications, defibrillation or implanting an artificial pacemaker. To help prevent arrhythmias avoid substances that might trigger or worsen an arrhythmia, including caffeinated beverages, alcohol, tobacco and certain medications.
