WebFigure 19.28 Relationship between the Cardiac Cycle and ECG Initially, both the atria and ventricles are relaxed (diastole). The P wave represents depolarization of the atria and is followed by atrial contraction (systole). Atrial systole extends until the QRS complex, at which point, the atria relax. The QRS complex represents depolarization ... WebJun 20, 2024 · Definition: Interruption of the normal conduction system leading to aberrant conduction and an abnormal QRS morphology Anatomy: At the AV node, conduction splits into the right and left bundle branches. The left bundle branch is composed of anterior and posterior branches. Right Bundle Branch Block (RBBB) Physiology
WebThe degree of blocking in the atrioventricular node is specified by counting the number of flutter waves preceding each QRS complex.
