Introduction

An arrhythmia, or irregular heartbeat, is a problem with the rate or rhythm of your heartbeat. 

Your heart may beat too quickly, too slowly, or with an irregular rhythm.

Arrhythmias are treatable with medicine or procedures to control the irregular rhythms.

 If not treated, arrhythmias can damage the heart, brain, or other organs.

 This can lead to life-threatening stroke, heart failure, or cardiac arrest.

 During cardiac arrest, the heart suddenly and unexpectedly stops beating, causing death if it is not treated within minutes.
