根据九省市小儿病毒性心肌炎协作组诊断标准,自1978年7月至1980年6月两年间对小儿病毒性心肌炎进行了发病调查,对其中1165例患儿初诊时的心电图改变分析如下:一、病期与年龄组本文1165例属急性期985例,～1个月16例;～3岁264例;～7岁291例;～14岁414例。恢复期52例,1个月～3岁1例;～7岁18例;～14岁33例。慢性期104例,1个月～3岁7例;～岁21例;～14岁76例。后遗症期24例,1个月～3岁2例;～7岁5例;～14岁17例。男630例,女535例。二、不同病期、年龄组心电图改变(表1)1.急性期985例,ST、T 改变占首位,为47%,其次为各型过早搏动45%,各型传导阻滞(包括束支传导阻滞)29.4%,房室增大
According to the diagnostic criteria of the collaborative group of children with viral myocarditis in nine provinces and cities, the incidence of viral myocarditis in children was investigated from July 1978 to June 1980, of which 1165 were analyzed as follows , Disease and age group of 1165 cases of this article are acute stage 985 cases, ~ 1 month 16 cases; ~ 3 years old 264 cases; ~ 7 years old 291 cases; ~ 14 years old 414 cases. Recovery period of 52 cases, 1 month to 3 years in 1 case; ~ 7 years in 18 cases; ~ 14 years in 33 cases.

There were 630 males and 535 females. Second, the different stages of disease, age group ECG changes (Table 1) 1. Acute phase in 985 cases, ST, T changes accounted for the first place, was 47%, followed by various types of premature beats 45%, various types of conduction block Branch conduction block) 29.4%, atrioventricular enlargement
