目的 探讨校正QTc离散度 (QTcd)与急性心肌梗死 (AMI)发生室颤的关系 ,比较 41例AMI与 45例非心肌梗死者 ,住院期间不同时期心电图QTcd。结果 AMI者室颤组 (AⅠ 组 )在室颤发生前的QTcd(73 .2 5± 9.45 )ms显著延长 ,此AMI之非室颤组 (AⅡ 组 )及非心梗之对照组 (B组 )有非常显著的差异 (4 2 .75± 7.2 4)ms、(3 0 .42± 9.19)ms,P <0 .0 1。认为QTcd对AMI室颤发生有预示作用
Objective To investigate the relationship between corrected QTc dispersion (QTcd) and ventricular fibrillation (VF) in patients with acute myocardial infarction (AMI) and to compare QTcd of 41 patients with AMI and 45 patients without myocardial infarction. Results The QTcd (73.25 ± 9.45) ms before VF in AMI patients was significantly longer than that in the non-VF group (AⅡ) and the non-myocardial infarction group (B) ) Had a significant difference (42.25 ± 7.24) ms, (3.42 ± 9.19) ms, P <0.01. QTcd that the occurrence of ventricular fibrillation AMI have a predictable effect
