What heart rate range is consistent with bradycardia?

Bradycardia is defined as a slower-than-normal heart rate, specifically a resting heart rate of fewer than 60 beats per minute. This condition can occur as a normal variant, particularly in well-conditioned athletes, but it can also be indicative of pathology or issues with conduction in the heart.

In the context of clinical assessment, recognizing bradycardia is essential because it may lead to inadequate cardiac output and could necessitate further evaluation or intervention, particularly if accompanied by symptoms such as dizziness, fatigue, or syncope.

The other heart rate ranges provided do not fall under the classification of bradycardia. A heart rate of 60-100 beats per minute is considered normal, while a rate exceeding 100 beats per minute indicates tachycardia, signifying a faster heart rate. Additionally, a rate between 40-60 beats per minute, although slower, does not strictly define bradycardia as it still falls within the lower limit potentially acceptable for some individuals, particularly athletes.
