Electrophysiologists treat heart arrhythmias and other heart rhythm disorders. These can include irregular heartbeats, including instances where the heart beats too quickly (tachycardia), and when the heart beats too slowly (bradycardia).
One of the most common arrhythmias that electrophysiologists treat is atrial fibrillation, also known as AFib. AFib occurs when the heart’s upper chambers—the atria—contract irregularly. AFib is the most common type of heart arrhythmia in the U.S., and it is a leading cause of blood clots that can result in a deadly stroke
