本文回顾性分析了101例小儿先心病右心导管术(RHC)中室性心律失常(VA)的发生率及其相关因素。结果,VA的总发生率为41%,其中伴短阵室速者为26%,需要处理者为8%。VA组术前电解质紊乱、复合畸形、右向左分流或双向分流、心室肥厚并劳损的发生率分别为:15/38、22/41、28/41、20/38;外周股动脉SaO_2为78.37±14.5%;右室收缩压为11.73±4.31kPa;与无VA组比较,差异有显著性(PO.O5)。
This paper retrospectively analyzed the incidence and related factors of ventricular arrhythmias (VA) in 101 children with congenital heart disease (RHC). As a result, the overall incidence of VA was 41%, with 26% of those with VT and 8% of those requiring treatment. VA group preoperative electrolyte imbalance, composite deformity, right to left shunt or bidirectional shunt, ventricular hypertrophy and strain incidence rates were: 15/38, 22/41, 28/41, 20/38; peripheral femoral artery SaO_2 was 78.37 ± 14.5%; RV systolic pressure was 11.73 ± 4.31kPa; compared with no VA group, the difference was significant (P <0.05). The average pulmonary pressure was 5.61 ± 3.21kPa, no significant difference between the two groups (P> O.O5).
