Abstract:
Objective To investigate the effect of acute intervention therapy on the QT dispersions(QTd)and correction QTd(QTcd)in patients with myocardial infarction. Methods112 patients with myocardial infarction who had received acute percutaneous coronary intervention(PCI)as study group,and divided it into three sub-group as Left anterior descending group,Left circumflex group and Right coronary group.70 infarction patients without acute intervention therapy as control group.And 12 lead standard surfaces ECG were recorded at beginning and 24h and 48h.respectively. ResultsAfter the PCI therapy,QTd and QTcd in study group improved significantly.However,QTd and QTcd had no difference among three sub-group. ConclusionThe acute intervention therapy could improve QTd and QTcd in patients with myocardial infarction.The vascular location had no difference in myocardial repolarization.
