WebDescription. Junctional rhythm is a regular narrow QRS complex rhythm unless bundle branch block (BBB) is present. P waves may be absent, or retrograde P waves (inverted in leads II, III, and aVF) either precede the QRS with a PR of less than 0.12 seconds or follow the QRS complex. The junctional rate is usually 40 to 60 bpm.

Web22 de oct. de 2024 · In general, there is no P wave identified before a premature QRS complex. However, there may be a normal sinus P wave present if the PVC is very late. In this situation, there is a long coupling interval (from the prior QRS complex), the P wave is not conducted, and the PR interval is shorter than the native sinus beat. WebIn most cases, the P-wave is not visible because when impulses are discharged from the junctional area, atria and ventricles are depolarized simultaneously and ventricular …

There are two non-distinct types of second-degree AV block, called Type 1 and Type 2. In both types, a P wave is blocked from initiating a QRS complex; but, in Type 1, there are increasing delays in each cycle before the omission, whereas, in Type 2, there is no such pattern.
