How does the QRS complex appear in a Junctional Bradycardia rhythm?

In Junctional Bradycardia, the QRS complex appears narrow and normal because the electrical conduction through the ventricles remains intact and is functioning properly. Junctional Bradycardia originates from the junctional tissues of the heart, which means the heartbeat is initiated in the AV node rather than the SA node, resulting in a slower heart rate. However, since the QRS complex, which represents ventricular depolarization, is generated under normal conditions despite the slower heart rate, it maintains a narrow configuration.

This narrow and normal appearance of the QRS complex is crucial for distinguishing Junctional Bradycardia from other types of bradycardia where the QRS may be wide or distorted due to dysfunction in ventricular conduction. Such characteristics help monitor technicians accurately identify and manage different cardiac rhythms effectively.
