Which term describes an abnormally slow heartbeat?

Bradycardia refers to an abnormally slow heartbeat, typically defined as a resting heart rate of fewer 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 and health conditions. Understanding bradycardia is essential for practical nurses, as it can become symptomatic or require intervention in specific patients.

In contrast, tachycardia denotes a rapid heartbeat, while tachypnea indicates an increased respiratory rate. Diaphoresis refers to excessive sweating, which can be associated with various medical conditions but does not relate specifically to heart rate. Recognizing the distinction between these terms is vital for effective patient assessment and care.
