What is defined as a pulse rate under 60 beats per minute?

The term that describes a pulse rate under 60 beats per minute is bradycardia. In the field of medicine, bradycardia is used to identify a slower than normal heart rate, which can be a normal physiological finding in athletes or individuals at rest. However, it can also indicate an underlying medical condition that may require evaluation or treatment. Understanding this condition is critical for health professionals, as bradycardia may affect blood circulation and overall health if it is too severe or symptomatic.

The other terms do not relate to heart rate: bruxism refers to the involuntary grinding of teeth, bronchoscopy is a procedure used to look inside the airways and lungs, and byasma appears to be a misspelling and does not correspond to any known medical term.
