Question 問題：

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）在兒童和成人中是一個相當(dāng)良性的心律紊亂。它與室性心律相似性導(dǎo)致誤診和不必要的治療。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是形狀一致的寬波室性心律，連續(xù)超過3個；除了在開始或結(jié)束時出現(xiàn)的融合波外，QRS波形不變化。成人中其（AVIR）心率很少超過120.
