Rapid heartbeat?

Explanation:
Rapid heartbeat means the heart is beating faster than normal. The term that matches this description is tachycardia. In adults, a resting heart rate above about 100 beats per minute defines tachycardia, which distinguishes it from bradycardia (slow heart rate). Palpitations describe the sensation of the heartbeat, which can occur with tachycardia but refers to how it feels rather than how fast it is. Arrhythmia refers to an irregular or abnormal rhythm, which may accompany a fast rate but centers on rhythm, not speed. So when the prompt describes a rapid heartbeat, tachycardia is the precise label.
