Atrial fibrillation with an uncontrolled ventricular response Left bundle branch block Premature ventricular contractions At times it can be difficult to distinguish "SVT with aberrancy" from ...

At times it can be difficult to distinguish "SVT with aberrancy" from ventricular tachycardia. This QRS morphology has a typical left bundle branch block pattern, is irregular and does not meet the ...

Complete heart block means that there’s a complete separation of electrical activity between the upper and lower chambers of the heart. Without prompt medical attention, it can be fatal. Your heart ...

First-degree ventricular (heart) block affects the electrical signal that makes the heart beat. It causes a delay in a portion of the heart beat and may lead to a slow heart beat. Healthcare ...

The rhythm is regular at a rate of 132 beats/min. The QRS complexes are wide (0.16 sec). Although the QRS complexes have a morphology that resembles a right bundle branch block (RBBB), with a tall ...
