对140例冠心病病人进行心室晚电位(VLP)检测,其中心绞痛组80人,心肌梗塞组60人。心肌梗塞组VLP阳性率明显高于心绞痛组(P<0.05);心肌梗塞伴有室性心律失常者VLP阳性率明显高于不伴有室性心律失常者(P<0.05),也明显高于伴有室性心律失常的心绞痛病人(P<0.05);心肌梗塞病人有8例发生室性心动过速,其中5例VLP阳性。提示VLP与心肌梗塞后出现室性心律失常,特别是出现室性心动过速密切相关。
Ventricular late potential (VLP) was measured in 140 patients with coronary heart disease, including 80 angina pectoris patients and 60 myocardial infarction patients. The positive rate of VLP in myocardial infarction group was significantly higher than that in angina group (P <0.05). The positive rate of VLP in myocardial infarction with ventricular arrhythmia was significantly higher than that in non-ventricular arrhythmia (P <0.05) Angina patients with ventricular arrhythmia (P <0.05); 8 patients with myocardial infarction had ventricular tachycardia, of which 5 were positive for VLP. Tip VLP and ventricular arrhythmia after myocardial infarction, especially the occurrence of ventricular tachycardia is closely related.
