AP variants Flashcards

5999111763	Atrium to the his bundle	Jahmes Fiber	0
5999111764	Fasciculoventricular	Very rare (short HV is the only finding)	1
5999111765	Concealed	___ (conducting V-->A) rate dependent AV pathways are fairly frequent.	2
5999111766	Latent	__ pathways conduct anterograde but very late and are thus not seen on ECG.	3
5999111767	Posteroseptal	AP that exhibit AVN-like features (called 'decremental AP') are most often___.	4
5999111768	Atriofascicular	Antegrade conducting, rate dependent AP, ie Maheim fibers. These are less common: the most frequent type is__ (usually AL part of TV--> RV apex)	5
5999235550	right sides	Antegrade conducting AV AP with rate-dependence are rare: these are usually __.	6
5999235551	LBBB	Rate dependent AF fibers often have nl ECG. With atrial stim, esp. near the AP, will show pre-excitation resembling___	7
5999235552	Nodoventricular	Ventricular pre-excitation with rate-dependence, sometimes called Mahaim, who originally ascribed these AP as____. We now know there are many forms.	8
