摘　　要：目的分析直立倾斜试验诱发短QT间期致心脏停搏的原因及护理策略。方法收集医院2018年2月至2020年11月在直立倾斜试验中诱发短QT间期致心脏停搏的8例血管迷走性晕厥患儿的病历资料,分析心脏停搏的原因及护理策略。结果8例患儿中,男3例,女5例,因头晕、反复晕厥就诊。体格检查无阳性体征,血生化、脑电图、头颅CT、心电图、心脏超声检查均正常。患儿在直立倾斜试验中心脏停搏2.2~11.4 s,心电图可见QT间期、QTc间期缩短。结论直立倾斜试验中迷走神经张力增高,可诱发短QT间期,引发心脏停搏。可分试验前、中、后3个阶段分别做好相应护理措施。Objective To analyze the causes and nursing strategies of cardiac arrest caused by short QT interval induced by head up tilt test.Methods The medical records of 8 children with vasovagal syncope induced by short QT interval in upright tilt table test from February 2018 to November 2020 were collected,and the causes of cardiac arrest and nursing strategies were analyzed.Results Among the 8 children,3 children were male and 5 children were female.They were treated for dizziness and recurrent syncope.Physical examination showed no positive signs,blood biochemistry,EEG,cranial CT,ECG and cardiac ultrasound were normal.In the head up tilt test,the cardiac arrest of children was 2.2-11.4 s,and the QT interval and QTc interval were shortened in ECG.Conclusion The increase of vagus nerve tension in head up tilt test can induce short QT interval and cardiac arrest.Corresponding nursing measures can be taken before,during and after the test.
