Atrial flutter is an abnormal heart rhythm that causes the atria to beat more quickly than they should.
Do cell phones interfere with pacemakers? Do ICDs need to be adjusted? Here are answers to these and other questions.
When you have heart block, there is interference with the electrical signals that usually move from the top chambers of your heart to the bottom chambers, telling your heart when to beat. Read on to learn about causes, symptoms, and treatment.

Sick sinus syndrome (SSS) is a type of abnormal heartbeat, or arrhythmia. If you have SSS, you may have episodes when your heart beats very slowly, stops beating for a short while, or beats very rapidly.
Ventricular fibrillation is a type of arrhythmia, or irregular heartbeat, that affects your heart's ventricles.
Ventricular tachycardia is a fast, abnormal heart rate that starts in the lower chambers of the heart. It can become life-threatening if it lasts more than a few seconds. Here's what you need to know about this condition.
Wolff-Parkinson-White syndrome (WPW) is a type of abnormal heartbeat. If you have WPW, you may have episodes of tachycardia, when your heart beats very rapidly
An AED is a small, portable, battery-powered machine with a computer in it. The machine detects heart activity. It can give an electric shock to someone if needed.
