Reentrant junctional tachyarrhythmias Flashcards
1
Q
where do reentrant junctional tachyarrhythmias usually occur?
A
AV junction or Kent bundle
2
Q
what is the general mechanism for reentrant junctional tachyarrhythmias?
A
reentry
3
Q
what are the three specific mechanisms of junctional tacchyarrhythmias?
A
AV nodal
orthodromic
antidromic
4
Q
what are the two general modes of AV nodal reentry?
A
slow and fast
5
Q
how can orthodromic conduction be differentiated from antidromic conduction?
A
orthodromic conduction has narrow QRS complexes
antidromic conduction has wide QRS complexes
