In medical terminology, what does "bradycardia" mean?

The term "bradycardia" is derived from the Greek words "brady," meaning slow, and "kardia," meaning heart. Therefore, it specifically refers to an abnormally slow heart rate, typically defined as a resting heart rate of fewer than 60 beats per minute in adults. Understanding this terminology is crucial as it helps healthcare providers assess a patient's cardiovascular condition and determine whether further evaluation or treatment is necessary.

In contrast, other options denote different heart rates or rhythms. An abnormally fast heart rate is known as tachycardia, a normal heart rate would fall within the range of 60 to 100 beats per minute, and an irregular heart rate could refer to arrhythmias, which are disruptions in the regular rhythm of the heartbeat. Being familiar with these terms enhances communication in clinical settings, as accurate terminology is essential in patient assessment and documentation.
