AVNRT 的诊断已不属新问题,但在诊断细节上仍有探讨的必要。一、房室结双径路合并室上速与隐匿性旁道合并室上速。二者在窦性心律或室上速发作时 QRS波都正常,逆传 P 波在体表心电图上都不易见;心动过速时食管心电图所示 R—P 间期>110ms 不都是旁道逆传,因为 FP 逆传右房间隔下部先除极,待激动传到左房后壁,R—P 间期已延长。有关房室传导时间跳跃式延长的标准也有商讨之处。因此,单凭临床或无创性电生理指标诊断房室结双径路合并室上速应慎重。近年研究证实隐匿性旁 The diagnosis of AVNRT is no longer a new issue, but there is still a need to explore the details of the diagnosis. First, atrioventricular node dual path merger supraventricular tachycardia and occult bypass pathways. Both sinus rhythm or supraventricular tachycardia QRS wave are normal, reverse P wave in the body surface ECG are not easy to see; tachycardia esophageal ECG shown R-P interval> 110ms are not all sidewalk Reverse pass, because FP reversed the right atrial septum lower first depolarization, to be excited to the left atrial posterior wall, R-P interval has been extended. There is also discussion about the leapfrog criteria for atrioventricular conduction time. Therefore, clinical or noninvasive electrophysiological indicators alone diagnosed atrioventricular nodal pathways combined with supraventricular tachycardia should be careful. In recent years, research confirmed occult parasite
