Atrial Tachycardia Flashcards
1
Q
Atrial Tach accounts for what percentage of SVTs?
A
5%
2
Q
A V-A-A-V response would be seen in what arrhythmia?
A
Atrial Tachycardia
3
Q
Earliest atrial activation comes from the posterior septum. What EGM would reflect this?
A
CS 9-10
4
Q
What is the most common mechanism for A. Tach?
A
automaticity
5
Q
Pacing during A tach. at a cycle length 10-20 msec shorter than the TCL is an attempt to do what?
A
Entrain
6
Q
the interval between the last pacing stimulus and the first return EGM
A
Post pacing interval
7
Q
True or False: A PPI - TCL difference of >115msec and a VAVA response would rule out atrial tach.
A
True
8
Q
Does Adenosine help in Atrial Tach?
A
nope
9
Q
What kind of pacing induces Atrial tach?
A
Incremental Pacing
