《急诊每日一题》加速性室性自主心律（AIVR）2021年1月

Question 问题：

Accelerated idioventricular rhythm is a typically benign dysrhythmia seen in both children and adults. Its similarities to ventricular tachycardia results in misdiagnosis and unnecessary treatment. What are the specific ECG features of AIVR? 

加速性室性自主心律（AIVR）在儿童和成人中是一个相当良性的心律紊乱。它与室性心律相似性导致误诊和不必要的治疗。AIVR典型ECG特征是什么？

Answer 答案：

AIVR is a monomorphic wide-complex ventricular rhythm of > 3 consecutive beats; the QRS morphology does not vary with the exception of fusion complexes often seen at the beginning and end. The rate is rarely > 120 bpm in adults。

AVIR是形状一致的宽波室性心律，连续超过3个；除了在开始或结束时出现的融合波外，QRS波形不变化。成人中其（AVIR）心率很少超过120.
