Accelerated ventricular rhythm typically presents with a heart rate in which of the following ranges?

Accelerated ventricular rhythm, often referred to as accelerated idioventricular rhythm (AIVR), is characterized by a ventricular rate typically ranging from 50 to 100 beats per minute (bpm). This condition usually occurs in situations such as myocardial infarction, particularly in the setting of reperfusion, where the heart experiences an increase in ectopic ventricular activity that does not reach the higher rates characteristic of ventricular tachycardia.

The heart rate in AIVR is important clinically, as it reflects the ability of the heart muscle to maintain perfusion during periods of ischemia, and is considered a relatively benign rhythm when compared to faster rates, such as those found in ventricular tachycardia.

Thus, the option indicating a range of 50-100 bpm is correct as it aligns with the typical presentation of this type of rhythm in clinical practice. This understanding is crucial for healthcare providers when assessing a patient’s cardiac status and deciding on appropriate management strategies.
