What is the heart rate range typically seen in idioventricular rhythm?

• A. 60-100 bpm
• B. 20-40 bpm
• C. 50-70 bpm
• D. 40-60 bpm

Answer: (B)

In idioventricular rhythm, the heart rate typically falls within the range of 20 to 40 beats per minute. This rhythm occurs when the ventricles become the primary pacemakers of the heart, usually due to a failure of the higher pacemaking tissues such as the sinoatrial node or atrioventricular node. The intrinsic rate of the ventricular pacemakers is naturally slower than that of atrial or junctional pacemakers, which accounts for the bradycardic heart rate observed in this rhythm. This characteristic heart rate is significant because it indicates that the heart's conduction system is not functioning optimally, which can lead to inadequate cardiac output and symptoms of low perfusion, such as dizziness or syncope. Recognizing this heart rate pattern is crucial in telemetry monitoring as it informs clinical decisions regarding patient management and potential interventions that may be required to restore a more effective heart rhythm.
