Of World Heart Rhythm Week
World Heart Rhythm Week is the Arrhythmia Alliance's annual week to raise awareness of arrhythmias. Arrhythmias are abnormalities in the heart's rhythm which can lead to complications like palpitations, fainting, stroke, and death. The most common sustained arrhythmia is atrial fibrillation, which affects two to nine percent of people in the United States.
The heart normally pumps 60-100 times per minute to circulate blood throughout the body. An electrical system inside the heart stimulates the heart muscle to pump with each heartbeat. Abnormalities in the heart's rhythm can result in extra or missed heartbeats, or the heart pumping too fast (tachycardia) or too slow (bradycardia).
