ＱＴ离散度(ＱＴｄ)指同一心电图各导联间ＱＴ时限变异的程度,是近年发展起来的一项评价心脏复极同步程度的指标。本研究旨在探讨急性心肌梗塞(ＡＭＩ)后早期ＱＴｄ及ＪＴ离散度(ＪＴｄ)与室性心律失常、心力衰竭及心源性死亡的关系。1 资料和方法11 一般资料 1993年1月～19
QT Dispersion (QTd) refers to the extent of QT variation between leads of the same ECG. It is an index developed in recent years to evaluate the degree of cardiac repolarization synchronization. This study aimed to investigate the relationship between early QTd and JT dispersion (JTd) and ventricular arrhythmia, heart failure and cardiogenic death after acute myocardial infarction (AMI). 1 Materials and Methods 11 General Information January 1993 ~ 19
