What term describes a slow heart rate, specifically less than 60 bpm?

Bradycardia is the correct term for a slow heart rate, defined as less than 60 beats per minute (bpm). This condition signifies that the heart is beating at a slower than normal pace, which can result from various factors including increased vagal tone, certain medications, or underlying health conditions. Identifying bradycardia is crucial in emergency care, as it can indicate significant cardiovascular issues, especially if accompanied by symptoms like fainting, dizziness, or fatigue.

The other terms do not describe a slow heart rate. Tachycardia refers to a fast heart rate, typically defined as greater than 100 bpm. Arrhythmia is a broader term encompassing any irregularities in heart rhythm, which can include both bradycardia and tachycardia, along with other rhythm disturbances. Palpitations describe the sensation of feeling one's heart beating rapidly or irregularly, but they do not specifically define a heart rate range. Understanding these distinctions is essential for proper assessment and response in emergency medical situations.
