This electrophysiology tracing demonstrates a graded postexcitation response of the retrograde limb of an orthodromic reentrant tachycardia circuit with varying His refractory VPB coupling intervals, which reiterates the decrementally conducting retrograde limb of the tachycardia circuit.
该电生理描记图显示了在希氏束不应期室性早搏耦合间期不同的情况下,顺向折返性心动过速环路逆向支的分级兴奋后反应,这再次证实了心动过速环路逆向支的递减传导。
