摘要
为研究急眭心肌梗死伴持续和非持续室性心动过速患者间Q-T离散度和其它心电图参数之间的关系。比较14例急性心肌梗死伴持续室性心动过速和26例伴非持续室性心动过速患者的心室Q-T离散度、Q-T和Q-T_c间期。结果显示持续和非持续室性心动过速患者之间的Q-T离散度以及相邻胸导联Q-T离散度差异有显著意义(110.1±7.80对80.8±4.4,105.9±6.9对67.6±4.0,P<0.01)。我们认为相邻导联Q-T离散度增大极易出现室性心动过速,Q-T离散度大于110ms有发生持续室性心动过速的危险。而Q-T离散度在80—110ms之间有非持续室性心动过速的可能性。
In order to study correlationship between patients with sustained ventricular tachycardia(VTs) and non-sustained ventricular tachycardia (NVTs) following a-cute myocardia infarction (AMI) in Q-T dispersion (Q-Td) and other ECG data, analyses were performed of 26 patients with NVTs and 14 patients with VTs following AMI in Q-Td Q-T and Q-Tc interval. Results showed: In 14 patients with VTs, Q-Td and Q-Td of adjacent precordial leads were significantly greater than those of 26 NVTs patients (110.1±7.8 vs 80. 8±4. 4, 105. 9±6. 9 vs 67. 6±4. 0, P<0. 01). We have come to conclusion that increase in Q-Td of adjacent leads might lead to VTs. And a Q-Ta> 110ms would bring about danger of VTs, whereas a Q-Td of 80-110ms might result in NVTs.
