摘要: 为证实维拉帕米用于急性心衰诱导的可行性,对杂种犬静点盐酸维拉帕米诱导心衰,并记录各项指标。结果:主动脉收缩压下降29%,主动脉舒张压下降27%,左心室压力最大上升速率(+dp/dt)下降47.5%,左心室压力最大衰减速率(-dp/dt)下降57.5%,心率下降30.6%,心排出量下降34.2%,心内膜下活力指数下降13.8%,冠状动脉血流量下降40.3%;而肺毛细血管楔压(简称肺毛压)上升70.5%.在维持量静点中,上述指标能维持在较稳定的水平。提示维拉帕米静脉注射可产生满意的心衰效果,不失为建立动物急性心衰模型的一种有效方法.

Abstract: To determine the role of verapamile in induction of acute heart failure, Inj. Verapamile and ten dogs were used in the experiment. The experimental procedure is as follows: ① general anesthesia and insertion of the monitoring lines, ② induction of acute heart failure with Verapamile, ③ the collection of data, ④ statisticse. The result shows that: after a satisfied induction of heart failure, there is a significant decrease in aortic systolic pressure (-29%), aortic diastolic pressure (-18.5%), +d p /d t (-47.5%), -d p /d t (57.5%), HR (-30.6%), Cardiac output (-34.2%), endocardial viability ratios (-13.8%), and coronary flow (-40.3%). However there is a significant increase in pulmonary capillary wedge pressure (70.5%). In conclusion, in the acute experiment, the administration of Verapamile is an effective mothed in animal model of heart failure.
