逆向传导

结论HPS异位电冲动逆向传导，阻滞窦性心律下传，促使室速/室颤反复发作而呈现电风暴现象。

Conclusions Ectopic electrical activity from HPS usually has retrograde conduction , inhibit the antegrade AV conduction , and hence force the repetitive occurrence of VT / VF which appears as ventricular electrical storm .

逆向传导不经常进行。

This retrograde conduction does not always take place .

异搏定抑制房室结逆向传导比抑制前向传导的作用大；

Verapamil depressed the retrograde conduction more than the anterograde conduction at AV node level ;

向上游航行（逆流行驶）逆向传导不经常进行。

Sail up a river , ie against the current This retrograde conduction does not always take place .

型连续夺获心房；IV型HPS逆向与前向传导交替。

Type IV showed alternation between retrograde and antegrade conduction of HPS electrical activity .
