摘  要:为观察经皮冠状动脉腔内成形术(PTCA)对心室晚电位(VLP)的影响,对38例冠心病患者PTCA前、后的信号平均心电图(SA-ECG)进行定性、定量分析和随访观察。时域分析发现,3例VLP阳性中的1例PTCA术后VLP消失,有5.7%(2/35)VLP阴性患者术后VLP转为阳性;频谱时间标测发现,4例VLP阳性中的2例术后VLP消失,有11.8%(4/34)VLP阴性患者术后VLP转为阳性;全组患者中,PTCA前、后SA-ECG参数的变化无显著性(P>0.05)。术后随访10.9±2.5(4~14)个月,未发生心律失常事件。提示PTCA可使VLP阳性的部分患者转阴;使很少部分患者VLP阴性转为阳性。To observe the effect of percutaneous transluminal coronary angioplasty (PTCA) on ventricular late potentials (VLP),signalaveraged electrocardiogram(SAECG) was assessed in 38 patients with coronary artery disease before and after PTCA by qualitative and quantitative analysis and longterm followup was performed.Results:one of three patients(with time domain analysis) or two out of four patients(with spectrotemporal mapping,STM) with VLP lost their VLP after PTCA,but there was no significant difference in the mean valve of SAECG variance before and after PTCA in all patients(P>0.05).There is no arrhythmic event in all patients after PTCA during 10.9±2.5(4~14) months followup period.Conclusion:Part of patients with VLP lose their VLP after PTCA.Reperfusion might improve the prognosis of patients with coronary artery disease.
