目的探讨心脏传导系统(CCS)病变与心律失常及心电图ST-T改变的关系。方法对12例有临床心电图异常改变的心脏标本作CCS组织学观察。结果(1)12例心电图异常者均见CCS有病变,包括有CCS脂肪浸润和(或)纤维化、淀粉样变、炎症、发育异常及出血等。(2)组织学显示急性炎症性改变者的心电图改变主要有:窦性心动过速、频发多源性室性早搏。(3)组织学显示慢性退行性改变者的心电图改变复杂多样:包括慢-快综合征、窦性心动过缓并室内分支传导阻滞、房室传导阻滞及心室内传导阻滞。(4)CCS病变可有心电图ST-T改变。结论CCS病变是心律失常及心电图ST-T改变的病理基础之一。
Objective To investigate the relationship between cardiac conduction system (CCS) and arrhythmia and ECG ST-T changes. Methods CCS histological examination of 12 cardiac samples with abnormal changes of clinical electrocardiogram was performed. Results (1) 12 cases of abnormal ECG were found in CCS lesions, including CCS fatty infiltration and / or fibrosis, amyloidosis, inflammation, dysplasia and bleeding. (2) histological changes showed acute inflammatory changes in ECG are: sinus tachycardia, frequent multi-ventricular premature beats. (3) Histological studies showed that patients with chronic degenerative changes had complicated and varied electrocardiographic changes: including slow-fast syndrome, sinus bradycardia and branch branch block, atrioventricular block and intraventricular conduction block. (4) CCS lesions may have ECG ST-T changes. Conclusion CCS is one of the pathological basis of arrhythmia and ECG ST-T changes.
