克山病心肌病变特点之一是播散性小灶性心肌坏死。粟粒状坏死灶大小相仿,数目众多,散漫分布于心肌全层,心内膜下心肌尤为严重。心室间隔位于两侧心室内膜下,该部病变严重,并且是双侧束支的行走部位,因此各种类型的束支传导阻滞是克山病常见的一项心电图改变。有关左束支分支传导阻滞及双侧束支传导阻滞的心电图特点及临床意义,日益受到广泛的重视。国内有关这方面的报告虽少,但认为并非罕见。两年来在我们观察的138例慢型克山病中就有左束支分支传导阻
Keshan disease is one of the characteristics of myocardial lesions disseminated focal myocardial necrosis. Miliary necrosis lesions of similar size, a large number, scattered throughout the myocardium, particularly severe endocardial myocardium. Ventricular septum is located on both sides of the subendocardium, the Department of serious disease, and is the walking of bilateral bundle branches, so various types of bundle branch block is Keshan disease is a common ECG changes. On the left bundle branch branch block and bilateral bundle branch block ECG characteristics and clinical significance, more and more widespread attention. Although there are few reports in this area in China, it is not uncommon. In the past two years, there were left bundle branch branch resistance in 138 cases of Keshan disease we observed
