Atrioventricular conduction

"Atrioventricular conduction" refers to the physiological process by which electrical impulses are transmitted from the atria to the ventricles via the atrioventricular node and the bundle of His[1][2][4]. This process plays a critical role in coordinating the timing of atrial and ventricular contractions, ensuring efficient pumping of blood throughout the circulatory system. Disruption or delay in AV conduction can result in arrhythmias, ranging from first-degree AV block (prolonged conduction) to complete heart block (absent conduction). While the process itself is not a molecular target, various drugs can modulate AV conduction, typically by acting on the ion channels and cell signaling pathways within the AV node.\n\nFor structured molecular target information, the correct entry would be "Atrioventricular node" (AV node), a specialized cluster of cardiac muscle cells, not "atrioventricular conduction" (the process).
