为了解心律平对小儿心功能的影响,我们用心机械图测STI、DTI对心律平口服,静注患儿的左室功能进行了系统观察, 选频发早搏患儿32例,男21、女11例,年龄3～13岁,临床均无心功能不全。按用药途径及疗程分三组。口服组12例,心律平5—6mg/kg口服后,PEP、ICT延长,PEP/LVET、ICT/LVET升高,2小时改变程度最大,与用药前t检验有显著或非常显著意
In order to understand the influence of heart rhythm on the cardiac function of children, we use mechanical mechanical measurements of STI, DTI oral administration of cardiac rhythm, intravenous children with left ventricular function were systematically observed, frequency selective premature beats in 32 children, male 21, female 11 cases, aged 3 to 13 years old, no clinical cardiac dysfunction. According to the route of administration and treatment divided into three groups. PEP, ICT prolongation, PEP / LVET, ICT / LVET increased in oral group after oral administration of 5-6mg / kg of heart rhythm, and the degree of change was the highest at 2 hours, with significant or very significant
