Slow heartbeat?

Explanation:
Slow heartbeat is bradycardia. In adults, a resting heart rate under 60 beats per minute is considered bradycardia. Some people, especially well-trained athletes, naturally have slower heart rates without symptoms, but when bradycardia causes dizziness, fainting, or fatigue, it may indicate an issue with the heart’s electrical system or require medical attention. Tachycardia means a fast heart rate (more than about 100 bpm at rest), which is the opposite concept. Hypertension refers to high blood pressure, not heart rate. Palpitations are the sensation of feeling the heart beat—racing, fluttering, or pounding—rather than a label for a slow rate.
