What is the definition of Bradycardia?

Bradycardia is defined as a slower than normal heart rate, specifically when the heart beats at a rate of fewer than 60 beats per minute in adults. It is important to note that a normal resting heart rate typically ranges between 60 to 100 beats per minute. Therefore, when the heart rate drops below this normal range, it is classified as bradycardia.

While the choice indicating a heartbeat below 110 is partially related to the definition, it does not accurately capture the specific threshold that defines bradycardia, which is less than 60 beats per minute. Understanding bradycardia includes recognizing its potential causes, such as increased vagal tone, certain medications, or underlying heart conditions, which all indicate that the heart is not beating fast enough to meet the body's metabolic demands.
