Junctional ( escape) Rhythm 4060 bpm Normal Sinus Rhythm Normal Sinus Rhythm Second Degree AV Block, Type 2 PR interval becomes progressively longer , until a P wave occurs without a QRS complex , after the pause the PR interval cycle starts again irregular treatment atropine or pacemaker Second Degree AV Block, Type 2Dec 02, 15Ventricular arrhythmias included premature ventricular complexes (PVCs) in 434%, >0 PVCs per 24 hours in 33%, multifocal PVCs in 53%, nonsustained ventricular tachycardia in 07%, and accelerated idioventricular rhythm in 03% Bradyarrhythmias included sinus pause >3 seconds in 03%, and seconddegree AV block in 24%Jun 13, 16The sinus P waves of the underlying rhythm can be seen just before the PVC in example A and after the PVC in the ST segment in example B These P waves are associated with the underlying rhythm (not the PVC) and usually are hidden within the wide QRS of the premature ventricular contraction Lesson V Ecg Rhythm Abnormalities Sinus rhythm w
