What is a significant heart rate concerning bradycardia?

Bradycardia is defined as an unusually slow heart rate, specifically one that falls below the normal range for resting heart rates in adults. Generally, a resting heart rate of fewer than 60 beats per minute is considered bradycardic. The significance lies in the potential implications for cardiac function and overall health; a heart rate below this threshold can lead to inadequate blood flow to the organs, resulting in symptoms such as fatigue, dizziness, or even fainting.

The critical component to understand here is that a heart rate under 60 beats per minute signifies a slowing of the heart that can be pathological, especially when associated with symptoms. Monitoring heart rates and identifying bradycardia helps healthcare professionals intervene appropriately, ensuring patient safety and optimizing care.
