WebIn integrative cardiovascular Chinese medicine, the study of the mechanisms of action in disease and recovery surveys the pumping actions of the heart by identifying the yin and yang phases of cardiac action potentials. Cardiac myocytes of the atria and ventricles connect and communicate impulses through gap junctions. Gap junctions are channels … WebThe speed at which an action potential propagates through a given region of cardiac tissue can be described as the relative conduction velocity (Figure 2). The propogation velocity varies considerably within regions of the …

WebAlthough early afterdepolarizations (EADs) are classically thought to occur at slow heart rates, mounting evidence suggests that EADs may also occur at rapid heart rates produced by tachyarrhythmias, due to Ca overload of the sarcoplasmic reticulum (SR) leading to spontaneous SR Ca release. We hypothesized that the mechanism of tachycardia-induced … WebAn action potential that occurs in a Purkinje myocyte. Purkinje myocyte action potential (Q22292771) From Wikidata. ...
