bradycardia


Bradycardia is a heart rate of less than 60 beats per minute. It can be caused by a problem with the heart's pacemaker, problems in the conduction pathways of the heart, metabolic problems such as hypothermia, or damage from heart disease . Symptoms of bradycardia can include fatigue, dizziness, lightheadedness, fainting or near-fainting spells, or, in extreme cases, cardiac arrest.
