Which term is defined as a rapid heartbeat?

• A. Bradycardia
• B. Tachycardia
• C. Arrhythmia
• D. Dyspnea

Answer: (B)

The term that describes a rapid heartbeat is tachycardia. This condition is characterized by a heart rate that exceeds the normal resting rate, which is typically 60 to 100 beats per minute in adults. Tachycardia can occur as a response to various factors such as stress, exercise, medications, or underlying medical conditions. It highlights the heart's response to increased demands for blood circulation, and understanding this term is essential for recognizing potential health issues related to heart function. Other terms in the list refer to different conditions: bradycardia indicates a slower than normal heart rate; arrhythmia refers to any irregularity in heart rhythm; and dyspnea describes difficulty in breathing, which is unrelated to heart rate.
