本文探讨了PGE_1对开胸麻醉犬心脏电生理及对冠状动脉前降枝结扎引起室性心律失常的预防作用。结果表明:①PGE_1可缩短房内传导时间,延长房室结传导时间;②PGE_1能延长心房及房室结功能不应期并可增加室颤阈值;③对冠脉结扎引起的室性心律失常也有一定的预防作用。
This article explored the preventive effect of PGE_1 on cardiac electrophysiology in canine thoracic anesthesia and ventricular arrhythmia caused by anterior descending coronary artery. The results showed that: ①PGE_1 can shorten the conduction time in the atrium and prolong the conduction time of atrioventricular node; ②PGE_1 can prolong the atrial and atrioventricular node function refractory period and increase the threshold of ventricular fibrillation; ③For ventricular arrhythmias caused by coronary ligation The preventive effect.
