What is the long term effects of lowered heart rate?

A consistently lowered heart rate, or bradycardia, can have various long-term effects depending on its underlying cause. If bradycardia is due to improved cardiovascular fitness, it may indicate a well-conditioned heart and can be beneficial. However, if it results from underlying health issues, it can lead to symptoms like fatigue, dizziness, or fainting, and may increase the risk of complications such as arrhythmias or heart failure. Monitoring and addressing the cause are crucial for long-term health.
