ST_(Ⅱ)、ST_(Ⅲ)抬高程度及其动态变化对右室梗塞的诊断意义

Significance of electrocardiogram ST_(Ⅱ),ST_(Ⅲ)elevation and dynamic changes in diagnosis of RVMI

对121例急性下、后壁心肌梗塞的心电图进行分析,结果显示:37例伴右室梗塞者33例(89.2%)ST段抬高Ⅲ>Ⅱ,84例不伴右室梗塞者13例(15.5%)ST抬高段Ⅲ>Ⅱ,二者有极显著性差异(P<0.001),尤其右室梗塞患者ST(?)抬高的动态变化与右胸导联ST段抬高均呈一过性.提示ST段抬高Ⅲ>Ⅱ对下、后壁梗塞合并右室梗塞具有一定的诊断价值.

Electrocardiograms of 121 cases of inferior poste-rior infarction were analysed. Results showed that 33(89.2%) of 37 cases with RVMI were ST(?) ↑ >ST(?)↑, and that of 84 cases without RVIM, 13(15. 5%)were ST(?) ↑ >ST(?)↑ . Difference was very prominant(P <0. 001), especially in 33 cases of RVMT withST(?) ↑>ST(?)↑. Elevation of dynamic changes andright chest leads have been proved to be of value in di-agnosis of ST(?)↑>ST(?)↑ in combination with RVMIand inferior posterior in farction.
