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.
To investigate the effect of thrombolytic therapy on ventricular late potentials in patients with acute myocardial infarction, the ventricular late potentials, ventricular arrhythmias and sudden death in 84 patients with acute myocardial infarction were observed.Results In thrombolytic group (n = 47) and non-thrombolytic group = 37). The positive rates of ventricular late potentials were 15%, 35% respectively. The incidences of ventricular arrhythmias were 13%, 32%, respectively. The mortality rates were 2%, 13% . The positive rates of ventricular late potentials in thrombolysis recanalization group (n = 28) and non-recanalization group (n = 19) were 7% and 26% respectively, and the incidences of ventricular arrhythmia were 4% and 26% (P <0.05), suggesting that thrombolytic therapy can reduce ventricular late-ventricular rate of attachment, ventricular arrhythmia and mortality in patients with myocardial infarction.
