A regular heart rate greater than 100 beats per minute is described as which of the following?

Explanation:
The main idea here is that tachycardia means a heart rate over 100 beats per minute, and if the rhythm remains regular and the electrical activity appears to originate from the sinus node, it’s called sinus tachycardia. In adults, a normal resting rate is roughly 60–100 bpm; when the rate is consistently above 100 while the rhythm stays regular and the P waves look normal before each QRS, it indicates sinus tachycardia. This distinguishes it from Normal Sinus Rhythm (60–100 bpm), Sinus Bradycardia (below 60 bpm), or Atrial Flutter (which shows distinctive flutter waves and a different rhythm pattern).
