【摘要】 为了解Q—T离散度在冠心病急性心肌梗死时对严重的室性心律失常或出现心功能不全时的应用价值,我们对54例急性心肌梗死患者入院3h内的心电图检测,将其心功能按照Killip临床分为四级,其Q—T离散度(Q—Td)显示与心脏的舒缩功能无关。但在持续性室性心动过速及心室颤动时显著增高。提示Q—Td可作为急性心肌梗死时严重室性心律失常的预测指标。更多还原

【Abstract】 To estimate the clinical value of Q -T dispersion (Q -Td) in severe ventricular arrhythmia and cardiac insufficiency associated with AMI, 54 patients with AMI were studied by recording their ECG within 3 hours after admission. According to Killip’s standard, 54 cases were divided into 4 grades. The results showed that Q -Td was no significantly differences from cardiac diastolic and systolic function but it was associated with ventricular tachycardia and ventricular fibrillation. It might be used as a predictor of severe ventricular arrhythmia in patients with AMI.更多还原
