右胸心电图曾被用于右室肥厚的诊断,而用于右室梗塞(RVI)的诊断则是近十几年来心电图临床应用的新进展。RVI绝大多数与左室梗塞(MI)并存。由于冠状动脉供血的区域特性,RVI可以是不同程度不同范围左室MI的延伸。尸解已发现左室下壁合并RVI,左室下壁合并孤立性右室乳头肌MI,左室前壁合并RVI,左室侧壁合并RVI,左室心内膜下合并RVI以及左室复合MI合并RVI等。其中以左室下壁、左室前壁MI合并RVI多见。本文着重综述这两型RVI的右胸心电图特征。正常人的右胸心电图完整的右胸心电图包括V_(1R)～V_(7R)7个导联,但因V_(1R)、V_(2R)就是常规V_2、V_1导联,其位于左右室共同部分的室间隔,大部分作者仍用V_2、V_1表示。V_(3R)～
Right chest electrocardiogram has been used for the diagnosis of right ventricular hypertrophy, and the diagnosis of right ventricular infarction (RVI) is the new progress of clinical application of ECG in recent ten years. The vast majority of RVI co-exist with left ventricular infarction (MI). Due to the regional characteristics of coronary artery blood supply, RVI may be an extension of left ventricular MI with varying degrees of range. Autopsy has been found in the left ventricular wall combined with RVI, left ventricular inferior wall combined with isolated right ventricular papillary muscle MI, left ventricular anterior wall merger with RVI, left ventricular wall with RVI, left ventricular endocardial combined with RVI and left ventricular complex MI merger RVI and so on. One of the lower left ventricular wall, left anterior wall MI combined with RVI more common. This article focuses on the right chest ECG characteristics of these two types of RVIs. Right intact right chest electrocardiogram of normal right chest ECG including V_ (1R) ~ V_ (7R) 7 leads, but because of V_ (1R), V_ (2R) is the conventional V_2, V_1 lead, which is located in the common room Part of the interventricular septum, most authors still use V_2, V_1 said. V_ (3R) ~
