A junctional rhythm typically ranges how many beats per minute?

A junctional rhythm typically ranges from 40 to 60 beats per minute. This heart rhythm originates from the area around the atrioventricular (AV) node rather than the sinoatrial (SA) node, which sets the natural pace for the heart. Since the junctional pacemaker takes over due to a failure of the SA node, it operates at this slower rate.

Understanding this range is important in recognizing the junctional rhythm, as it informs clinical assessment and potential management of patients who may present with this type of dysrhythmia. The presence of a rate between 40 and 60 bpm indicates that while the heart is conducting, it is doing so at a reduced pace, which may lead to symptoms of low cardiac output, particularly if the patient has underlying conditions. This critical knowledge is essential for anyone learning about cardiac rhythms.
