The study of long-term ventricular late potential in the acute myocardial infarction / 中国实用内科杂志

ABSTRACT

Objectives This study aimed at finding cut if reperfusion could be identified by long term VLP,using digital Holter ECG.Methods 24 hour 3 channel digital Holter recorders were performed on 38 patients with AMI before thrombolytic therapy,then the patients were divided into successful reperfusion group and unsuccessful reperfusion group.Every parameter was comparied between the two groups.Results VLP parameters showed a gradual improvement in the acute phase of MI in patients with successful reperfusion compared with those of unsuccessful reperfusion and that a significant difference between these two groups became evident from 2～3 hour after thrombolysis.Conclusions Our investigation certifies that successful reperfusion reduces VLP positive rate significantly 2～3 hours after thrombolysis.Thus,long term ventricular late potential may be helpful for identification of the reperfusion in AMI patients.In the mean time,Our study is performed before the formation of myocardial fibrous scar in AMI patients,it breaks up the traditional concept that VLP only developed from the formation of myocardial fibrous scar.
