Bradycardia

Bradycardia is a condition where the heart rate is slower than normal, usually less than 60 beats per minute. It can develop gradually or suddenly, and can be caused by a variety of medical conditions. Symptoms of bradycardia can include fatigue, lightheadedness, shortness of breath, and chest pain. It can also cause an irregular heartbeat, or palpitations. Treatment for bradycardia may include lifestyle changes, medications, or a pacemaker.
