What is a rhythm originating from the av node?

A rhythm originating from the atrioventricular (AV) node is known as a junctional rhythm. This occurs when the SA node fails to initiate the heartbeat, causing the AV node to take over as the primary pacemaker of the heart. Junctional rhythms typically have a rate of 40 to 60 beats per minute and may present with inverted or absent P waves on an electrocardiogram (ECG), as the atria and ventricles depolarize simultaneously. This type of rhythm can indicate underlying issues with the heart's normal conduction pathways.
