自1921年Einthoven 发现U 波以来,国内外对U 波的研究取得了不少进展,使其成为临床心电图诊断中不可忽视的波形之一。从五十年代开始,一些作者从不同角度对倒置U 波进行了观察,认为U 波倒置是提示有心脏病存在的一个高度特异的指标。近年来,我们从住院(92例)和门诊(12例)病人中共获得心电图具有倒置U 波的104例。本文旨在对倒置U 波与临床资料的关系、U 波逆转的影响因素和U 波起源的机制略加讨论。
Since Uinth Wave was discovered by Einthoven in 1921, much progress has been made in the study of U waves at home and abroad, making it one of the undisputed waveforms in clinical ECG diagnosis. Since the 1950s, some authors have looked at inverted U-waves from different angles, arguing that U-wave inversion is a highly specific indicator of the presence of heart disease. In recent years, we have obtained 104 patients with inverted U wave in the electrocardiogram from hospitalized patients (92 cases) and outpatients (12 cases). The purpose of this paper is to discuss the relationship between inverted U wave and clinical data, the influencing factors of U wave reversal and the origin of U wave.
