摘要
为探讨Q-T_e离散度与老年急性心肌梗死发生心室颤动的关系,比较60例老年急性心肌梗死者与73例非心肌梗死者住院期间不同时期心电图Q-T_e离散度.结果急性心肌梗死患者心室颤动组心室颤动发生前的Q-T_e离散度(74.0±30.3ms)显著延长,比非心室颤动组及对照组患者差异有非常显著意义(43.8±26.7ms、27.5±14. 8ms, P<0.01).认为Q-T_e离散度对老年急性心肌梗死心室颤动发生有预示作用.
In order to study relationship between Q-Tc dispersion and ventricular fibrillation in senile patients with AMI, authors have compared despersion of 60 senile patients with AMI and 73 cases without MI (control group)during their hospitalization. Result has shown: Q-Tcd of Vf group (74.0?30.3ms) is much longer than that of patients without-Vf(43.8?6.7ms) and of control groups(27.5?14.8ms)(P< 0.01). Authors assume Q-Tcd is very useful in predicting occurrence of Vf in senile patients with AMI.
