心脏传导系统简易检查法及常见致猝死病变(附51例观察)

A SIMPLIFIED TECHNIQUE FOR THE EXAMINATION OF CARDIAC CONDUCTING SYSTEM AND ITS PATHOLOGICAL FINDING IN SUDDEN DEATH (REPORTS OF 51 CASES)

报告一种适用于常规检查心脏传导系统的简易取材法,采用该法检查了70例正常人和51例无心外原因猝死者(按WHO规定起病后24h内死亡为猝死)的心脏传导系统(CCS)。CCS的病变有炎症、出血、脂肪浸润、纤维化、神经病变、窦房结和房室结动脉壁增厚、结构变异和淋巴细胞聚集等。51例中有15例(29％)应认为猝死系由CCS病变所致,包括炎症(8例)、出血(4例)、重度脂肪浸润(2例)和纤维化(1例)。

A convenient method for sampling cardiac conducting system (CCS) was reported. Slices of CCS from 70 normal persons and 51 cases of sudden death without extracardiac cause of death were observed (according to the regulation of The World Health Organization, oneset of disease death within 24 designates as sudden death). The pathological findings of the CCS include inflammation, hemorrhage, fatty infiltration, fibrosis, neuropathies, thickening of wall of nodal artery, structural abnormalities and focal aggregation of lymphocytes. Among 51 cases of sudden death, 15 (29%) cases were considered to be died of pathological changes of CCS. The attributable changes were inflammation (8), hemorrhage (4), severe fatty infiltration (2) and fibrosis (1).
