溶栓疗法对急性期心肌梗死心室晚电位的影响

为探讨溶栓对急性心肌梗死心室晚电位的影响,观察84例急性心肌梗死患者心室晚电位、室性心律失常及猝死的情况.结果溶栓组(n=47)与非溶栓组(n=37)心室晚电位阳性率分别为15%、35%,室性心律失常发生率分别为13%、32%,死亡率分别为2%、13%,差异均有显著意义(P<0.05).溶栓再通组(n=28)与未再通组(n=19)心室晚电位阳性率分别为7%、26%,室性心律失常发生率分别为4%、26%,差异均有显著意义(P<0.05).提示溶栓治疗能降低心肌梗死患者的心室晚电位附性率、室性心律失常发生率及死亡率.

Influence of thrombolysis on ventricular late potentials In acute myocardial Infarction

To teat influence of thrombolysis on ventricular late potentials in acute myocanlial infarction, we studied 84 patients with acute my-ocardial infarction. In 47 patients treated with thrombolysis, us compared with 37 patients treated conventionally, occurrences of venlres ular late potential(VIP)and ventricular arrhythmia(VA)and mortality rate were 15% vs.35%, 13% vs.32%, 2% vs.13% respectively (P < 0.05) .In comparison with nonreperfusion group(n = 19),occurrences of VLP and VA were less frequent in patients with reperfusion (n = 28), positive rates were 7% vs. 26% , 4% vs.26% respectively(p < 0.05) .Our data suggested that successful thrombolytic therapy was associated with a reduction in incidence of VLP, throm-bolytic therapy associated with late potentials denoted an excellent prognosis.
