A heart rate of 60-100 bpm is classified under which rhythm?

A heart rate of 60-100 beats per minute is considered to be within the normal range, particularly reflecting a state known as "normal sinus rhythm" when associated with sinus activity. The classification in question relates to specific junctional rhythms, particularly the accelerated junctional rhythm.

The accelerated junctional rhythm is characterized by a heart rate that ranges from 60 to 100 bpm, and it arises from the junctional tissues of the heart, which include areas around the AV node. In conditions where the sinoatrial (SA) node fails to initiate impulses or there is a failure of the SA node to take control due to a variety of reasons (like increased vagal tone or cardiac ischemia), the junctional tissue can take over as the pacemaker, hence the rate observed can accelerate up to this range.

In contrast, other rhythms listed exhibit significant differences in heart rate and origin. Junctional escape rhythm tends to occur at a slower rate, usually under 60 bpm, showing a slower intrinsic firing rate of the pace from junctional tissue that steps in due to failure from the SA node. Atrial tachycardia involves a rapid rate exceeding 100 bpm, originating from ectopic activity in the atria. Ventricular escape
