Causes & Risk Factors

Doctors don’t always know what causes paroxysmal atrial fibrillation. It often happens because things like coronary heart disease or high blood pressure damage your heart. If that damage affects the part of your heart that sends the electrical pulses that control your heartbeat, those pulses can come too fast or at the wrong time.
