Tachycardia is best defined as which of the following?

Explanation:
Tachycardia means a rapid heart rate. In adults at rest, a heart rate over about 100 beats per minute is generally considered tachycardia. This definition focuses on how fast the heart is beating, not on whether the rhythm is regular or irregular. The other descriptions describe a slow rate (bradycardia), no heartbeat (asystole), or an irregular rhythm with alternating fast and slow beats, none of which capture the idea of an elevated rate defining tachycardia.
