以往对心跳骤停复苏后心肌功能不全的研究多偏重于冠状动脉引起的局部心肌缺血,对整个心肌缺血涉及较少。本实验通过心室内导管电刺激诱发猪心室纤颤后,采用心前区胸外按压机械通气和电除颤模拟临床心跳骤停复苏过程,观察心脏复苏成功后心肌功能和代谢的 Previous studies of cardiac dysfunction after cardiorespiratory arrest recovered more from the localized myocardial ischemia caused by coronary arteries, with less involvement of the whole myocardial ischemia. In this study, after ventricular catheter electrical stimulation induced porcine ventricular fibrillation, pre-cardiac chest compressional mechanical ventilation and defibrillation were used to simulate the process of clinical cardiac arrest and recovery, and to observe myocardial function and metabolism after successful cardiac resuscitation
