4 Steps of Cardiac Conduction - ThoughtCo

WebThis electrical system is called the cardiac conduction system. It is made up of specialized tissues and cells embedded in the heart that send impulses directly to the atria and ventricles, causing them to contract. In the normal cardiac cycle, the left and right atria contract together first followed by the contraction of the ventricles together. WebAtrioventricular (AV) block occurs when the normal electrical impulse is unable to cross from the priming chambers (the atria) into the pumping chambers (the ventricles). There are varying degrees of atrioventricular block. Patients that have 1 st degree AV block require no specific therapy. Second degree AV block is incomplete, which means ... WebFigure 1.
