PPT-BLOQUEO AURICULO-VENTRICULAR

DRA SILVIA CERDA ADAME TORRE QUALITY JULIO 2015 El bloqueo auriculoventricular AV es un retardo o interrupción del impulso eléctrico proveniente del nodo sinoauricular a nivel del nodo . Learning Outcomes. During diastole blood returning to the atria flows into the ventricles. Atrial systole transfers the remainder of the blood through the atrioventricular (AV) valves to the ventricles. Ventricular systole closes the AV valves and pumps the blood out through the semi lunar (SL) valves to the aorta and pulmonary artery. In diastole the higher pressure in the arteries closes the SL valves. The opening and closing of the AV and SL valves are responsible for the heart sounds heard with a stethoscope. .
