目的:探讨婴儿阵发性室上性心动过速(PSVT)的心电图分型和药物治疗情况,总结药物治疗经验。方法:分析38例婴儿PSVT入院后的临床资料和药物治疗情况。结果:房室折返性心动过速(AVRT)17例(44.7%),房室结折返性心动过速(AVNRT)12例(31.6%),自律性房性心动过速2例(5.2%),未分型7例(18.4%),合并器质性心脏病11例(28.9%)。AVRT患儿用普罗帕酮转复率为100%,ATP为75.0%,地高辛为37.5%;AVNRT用普罗帕酮转复率为90.0%,ATP为83.3%,地高辛为40.0%,胺碘酮为66.7%。结论:正确的心电图分型对婴儿PSVT治疗药物的选择有指导意义,不同药物对不同类型的PSVT的治疗效果不同。
Objective: To investigate the electrocardiogram classification and drug treatment of paroxysmal supraventricular tachycardia (PSVT) in infants and summarize the experience of drug treatment. Methods: The clinical data and medication of 38 infants with PSVT after admission were analyzed. Results AVRT occurred in 17 cases (44.7%), atrioventricular nodal reentrant tachycardia (AVNRT) in 12 cases (31.6%) and spontaneous atrial tachycardia in 2 cases (5.2%). , Undifferentiated type in 7 cases (18.4%), combined with organic heart disease in 11 cases (28.9%). AVRT children with propafenone 100% conversion rate, ATP was 75.0%, 37.5% digoxin; AVNRT propafenone with 90.0% conversion rate, ATP 83.3%, digoxin 40.0% Amiodarone was 66.7%. Conclusion: Correct electrocardiogram classification is of guiding significance for the selection of PSVT in infants. Different drugs have different therapeutic effects on different types of PSVT.
