注釋

1.Coumel's sign指Coumel征或定律，當(dāng)預(yù)激綜合征發(fā)生順傳型房室折返性心動過速時，如旁道同側(cè)存在束支傳導(dǎo)阻滯，且旁道位于心室游離壁，那么，R-R間期（TCL）將比無束支阻滯時延長35ms以上。本文病例經(jīng)希氏束區(qū)起搏，奪獲希氏束同時激動左右心室并經(jīng)左外側(cè)旁道逆?zhèn)餍姆康腣-A間期明顯短于只奪獲右心室（未能奪獲希氏束），再經(jīng)左外側(cè)旁道逆?zhèn)餍姆康腣A間期，差值達52ms，也符合該征。

2.His-synchronous PVC與His-refractory PVC同義，均指在希氏束不應(yīng)期時的室性期前搏動。

3.句子"Although the presence of a septal AP,which is close to the AVN,may be ruled out with the results of these maneuvers,an LL-AP may not be with these maneuvers."中的LL-AP may not be后省略了"ruled out"。完整的句子應(yīng)該是"Although the presence of a septal AP,which is close to the AVN,may be ruled out with the results of these maneuvers,an LL-AP may not be ruled out with these maneuvers."
