What causes bradycardia? Causes of bradycardia include: Problems with the sinus node, the heart’s natural pacemaker What causes a low heart rate? "The most common cause of bradycardia is age-related degenerative changes in the heart's conduction system," says Dr. Matthew Yuyun, a cardiologist at Harvard-affiliated Brigham and Women's Hospital. Most pathological causes of bradycardia result from damage to this normal cardiac conduction system at various levels: the sinoatrial node, the atrioventricular node, or damage to conduction tissue between or after these nodes.
