A slow heartbeat, or bradycardia, can occur for various reasons, including increased physical fitness, certain medical conditions, and the effects of medications. Athletes often experience bradycardia due to a well-conditioned heart that pumps more efficiently. Additionally, conditions like hypothyroidism, heart block, or aging can affect the heart's electrical system, leading to a slower heart rate. In some cases, bradycardia may not cause symptoms, but if it leads to dizziness or fatigue, medical evaluation is recommended.
