迄今,国内外对家兔急性心肌缺血时心外膜电图的变化尚未见报道。本文观察了10例家兔急性心肌缺血时心脏不同部位心外膜电图的变化规律及其与血压变化的关系,为进一步利用家兔心外膜电图开展急性心肌缺血的研究打下了一定的基础。方法动物:家兔10只,雌雄兼有,体重1.75—2.55kg。麻醉:20%乌拉坦溶液5-6ml/kgiV。手术及实验:仰卧位固定动物,做颈总动脉插管测血压;开胸、做心包摇篮后在家兔心脏冠脉左室支中1/2处套可以000号双道丝线备结扎时用。用无创伤缝合针做电极、细漆包线做
Up to now, the changes of epicardiogram at home and abroad on rabbit acute myocardial ischemia have not been reported yet. In this paper, we observed the changes of epicardial electrocardiogram (ECG) in different parts of the heart and the relationship with the changes of blood pressure in 10 rabbits with acute myocardial ischemia. This study laid the foundation for the further study of rabbit acute epimyocardial ischemia A certain basis. Methods Animals: 10 rabbits, both male and female, body weight 1.75-2.55kg. Anesthesia: 20% of urethane solution 5-6 ml / kgiV. Surgical and experimental: supine fixed animals, to do carotid artery cannulation to measure blood pressure; thoracotomy, do cradle cradle in rabbit heart coronary artery left ventricular branch in 1/2 can be set to 000 dual-wire preparation for ligation . Electrode with non-invasive suture needle, fine enameled wire to do
