Bradycardia

Bradycardia is a condition in which the heart rate is abnormally slow, defined as a resting heart rate below 60 beats per minute. It is caused by malfunctioning or underactive electrical pathways in the heart, which can damage the heart muscle and reduce its ability to pump blood. Bradycardia can be caused by a variety of conditions, including medications, medical conditions such as thyroid disease or diabetes, and genetic defects. Symptoms of bradycardia can include fatigue, dizziness, lightheadedness, fainting, and shortness of breath. Treatment depends on the underlying cause and may include lifestyle modifications, medications, or a pacemaker.
