As a medical professional with expertise in cardiology, I can provide you with an explanation of a PJC heart rhythm.
Premature Junctional Contractions (PJCs) are extra, early heartbeats that originate from the atrioventricular (AV) junction, which is the electrical pathway between the atria and the ventricles of the heart. These contractions are premature because they occur earlier than the regular cycle of the heart's rhythm.
When a PJC occurs, it causes an early cardiac complex that disrupts the underlying rhythm. The locus of stimulation being different from the normal pacemaker (the sinus node), results in a change in the morphology of the P wave, which can be inverted if it is visible on an electrocardiogram (ECG). PJCs can occur occasionally or frequently, and while they are generally not dangerous, they can be a sign of an underlying condition that should be evaluated by a healthcare professional.

PJCs. This early impulse causes an early cardiac complex which disrupts the underlying rhythm. The locus of stimulation being different, results in a change in the morphology of the P wave (inverted if it can be seen). PJC's can occur occasionally or frequently.
