The correct diagnosis is normal sinus rhythm, right bundle branch block (RBBB), left anterior fascicular block, bifascicular disease, blocked (nonconducted) premature atrial complexes in a trigeminal ...

The normal physiologic range of QRS complex duration spans between 80 and 125 ms with known differences between females and males which cannot be explained by the anatomical variations of heart sizes.

The correct diagnosis is accelerated idioventricular rhythm (slow ventricular tachycardia) (Figure 2). Although recent oral surgery could suggest endocarditis, it is not definitively present. The ...

Pace mapping and visual comparison of the local pacing response with the intrinsic QRS morphology form the mainstay of His bundle pacing (HBP). We evaluated the performance of a surface lead ...

The three irregularly irregular rhythms are atrial fibrillation, atrial flutter with variable conduction and multifocal atrial tachycardia (similar to wandering atrial pacemaker). Atrioventricular (AV ...
