Which term describes a slow heartbeat?

Bradycardia is the term used to describe a slow heartbeat, specifically when the heart rate is less than 60 beats per minute in adults. This condition can occur in various situations, including during sleep, in well-trained athletes, or as a response to certain medications or heart conditions. Understanding bradycardia is essential in emergency situations, as it can indicate underlying health issues that may require medical attention.

Tachycardia refers to a heart rate that is faster than normal, typically over 100 beats per minute. Apnea describes a temporary cessation of breathing, which is not directly related to heart rate. Hypertension relates to high blood pressure and, while it can affect heart function, it does not describe heart rate itself. By recognizing bradycardia, responders can better assess a patient's condition and determine the appropriate course of action.
