摘要
50例陈旧性心肌梗塞(OMI)患者利用动态心电图(DCG)分析系统进行了心室晚电位(Ventricular Late Potential,VLP)检测.结果发现:(1)OMI患者VLP阳性率为22%(11/50例);(2)VLP检测OMI有非持续性室速者其阳性率为75.0%,而无非持续性室速者VLP阳性率为17.4%,两者相比,差异十分显著(P<0.01);(3)VLP阳性与梗塞部位、室性早博、心功能不全、室壁瘤形成等无明显相关.
In order to minimize the cardiogenic sudden death in patients with old my-ocardial infarction(OMI)and increase the accuracy of long term prognosis,a study of ventricular late potential (VLP) was made in 50 cases with OMI using the dynamic electrocar-diographic analytical system. 90 healthy persons were used as control. It was found in our study:(1)The positive rate of VLP was 22%(11/50cases) in patients with OMI; (2)The VLP positive rate was 75% in OMI patients with nonpersistent ventricular tachycardia,and 17. 4 % without nonpersistent ventricular tachycardia, the difference was significant (P< 0. 01); (3)There was no close correlation between the positive VLP with the MI location, ventricular premature beats,ventricular dysfunction and ventricular aneurysm.
