A PJC arises from an irritable focus within the AV junction. Characteristics of a PJC include: 1) an absent or inverted P wave in lead II; 2) a shortened PR interval - less than .12 seconds; and 3) the complex comes early or premature.
The process involves conducting an electrocardiogram (ECG), gathering medical history, performing a physical examination.
Treatment for NSR with Premature Junctional Contractions (PJC) includes adjusting or stopping digitalis, managing toxicity, and treating underlying conditions.
