近年来,人们对左室肥大的心电图诊断进行了大量的研究,除电压标准外,1981年 Beach等报道了非对称性倒置 T 波、其非对称性比例≥2.0对左室肥厚或扩张的诊断价值。1984年 Short 等又报道了 T 波终末正向超射与左室肥大密切相关。为此我们对一组正常人和一组左室肥大病人,以超声心动图与心电图进行了系统的、对比性、前瞻性研究,旨在进一步探讨此两个单项标准对左室肥大的诊断价值。对象和方法一.对象(一)正常对照组:共54例。其中男24例,女30例,年龄16—56岁(平均34.8岁)。均无心血管病的病史,体征及实验室证据。(二)左室肥大组:共81例。其中男55例,女26例。年龄16—81岁(平均46.7岁)。
In recent years, a large number of studies have been conducted on ECG diagnosis of left ventricular hypertrophy. In addition to the voltage standard, Beach et al. Reported an asymmetric inverted T wave in 1981 with a diagnosis of left ventricular hypertrophy or dilatation with an asymmetry ratio of ≥2.0 value. 1984 Short also reported the final positive T-wave and left ventricular hypertrophy are closely related. To this end, we conducted a systematic, comparative and prospective study of a group of normal subjects and a group of patients with left ventricular hypertrophy using echocardiography and electrocardiography to further explore the diagnostic value of these two individual criteria for left ventricular hypertrophy . Subjects and methods I. Objects (a) normal control group: a total of 54 cases. There were 24 males and 30 females, aged 16-56 years (average 34.8 years). No history of cardiovascular disease, signs and laboratory evidence. (B) left ventricular hypertrophy group: a total of 81 cases. There were 55 males and 26 females. Age 16-81 years (average 46.7 years old).
