本文用M型超声心动图方法计算的左心室重量(LVM)作对照,评价心电图诊断左心室肥大的准确性。103例心脏病患者,分成左心室肥大(LVM男性>210g,女性>188g)和左心室不肥大两组。被评价的左心室肥大心电图诊断标准计23项,包括QRS电压、电轴左偏、左室劳累型ST段压低、VAT和Ptfv_1等单项标准,Sokolow-Lyon胸导联综合电压标准,Romhilt-Estes计分法(RE计分法)和山东医学院的计分法。本文并提出一种修改后的计分法,它与RE计分法相比,敏感度从51.22％提高到58.54％,准确度从79.61％提高到82.52％,特异度保持98.39％。
In this paper, M-mode echocardiography calculated left ventricular mass (LVM) as a control to evaluate the accuracy of ECG diagnosis of left ventricular hypertrophy. 103 patients with heart disease, divided into left ventricular hypertrophy (LVM male> 210g, female> 188g) and left ventricular hypertrophy two groups. Twenty-three criteria were evaluated for the diagnosis of left ventricular hypertrophy, including QRS voltage, left axis deviation, left ventricular fatigue ST segment depression, VAT and Ptfv_1, Sokolow-Lyon thoracic lead voltage, Romhilt-Estes Scoring (RE Scoring) and Scoring at Shandong Medical College. In this paper, a modified scoring method is proposed. Compared with RE scoring method, the sensitivity of scoring method is improved from 51.22% to 58.54%, the accuracy is improved from 79.61% to 82.52%, and the specificity is 98.39%.
