摘要 目的探讨缬沙坦对豚鼠心室肌电生理的影响。方法 30只豚鼠随机分为对照组、阳性药组和缬沙坦组各10只。缬沙坦组给予缬沙坦80 mg/kg,阳性药组给予硫酸奎尼丁50 mg/kg,对照组给予等体积生理盐水(2min注射完)。测定各组用药前后不同时间点的平均动脉压、心率、心室有效不应期和心室颤动阈值的变化。结果用药后40、60 min阳性药组和缬沙坦组平均动脉压和心率均低于对照组(P均<0.05),心室有效不应期较对照组均明显延长(P均<0.01),心室颤动阈值较对照组均明显提高(P均<0.01)。结论缬沙坦能改善豚鼠血流动力学状况,延长心室肌有效不应期,提高心室颤动阈值,有潜在的抗心律失常作用。
