What is the inherent rate of the AV junction?

20-40 bpm
40-60 bpm
60-100 bpm
100-120 bpm

The correct answer is: 40-60 bpm

The inherent rate of the AV junction, also known as the atrioventricular node, typically falls within the range of 40-60 beats per minute (bpm). This rate reflects the intrinsic ability of the AV node to generate electrical impulses when the primary pacemaker of the heart, the sinoatrial (SA) node, is not functioning effectively or is not stimulating the heart at a normal rate. The AV junction acts as a secondary pacemaker, capable of taking over in instances where there is a disruption in the heart's normal rhythm. Its slower rate compared to other pacemakers, such as the SA node (which has a rate of 60-100 bpm), means that while it can maintain cardiac rhythm, it does so at a pace that is less than optimal for most physiological needs. This understanding is essential for managing patients with arrhythmias and underscores the role of different cardiac conduction pathways in maintaining an effective heartbeat.
