What type of heart rhythm may be triggered by a Premature Junctional Contraction (PJC)?

A Premature Junctional Contraction (PJC) is a type of ectopic beat that originates in the junctional area of the heart, which is located between the atria and the ventricles. PJCs can disrupt the normal heart rhythm by eliciting additional heartbeats. When a PJC occurs, it can rapidly lead to a sequence of beats because it may create a momentary disturbance that increases the automaticity of the nodes in the heart, particularly the junctional tissue.

Junctional Tachycardia is characterized by a heart rate of greater than 100 beats per minute that arises from this same junctional area. Since a PJC can initiate a series of junctional beats, it is feasible for it to trigger junctional tachycardia when the junctional pacemaker takes over. Therefore, the connection between PJCs and the rise of junctional rhythm reflects how ectopic impulses can alter cardiac conduction.

The other options, such as Atrial Fibrillation, Ventricular Escape Rhythm, and Sinus Bradycardia involve different pathways and mechanisms. Atrial Fibrillation arises from disorganized electrical activity in the atria, while Ventricular Escape Rhythm typically results from a failure of the higher pacemakers, allowing
