1

Atrial Tach accounts for what percentage of SVTs?

5%

2

A V-A-A-V response would be seen in what arrhythmia?

Atrial Tachycardia

3

Earliest atrial activation comes from the posterior septum. What EGM would reflect this?

CS 9-10

4

What is the most common mechanism for A. Tach?

automaticity

5

Pacing during A tach. at a cycle length 10-20 msec shorter than the TCL is an attempt to do what?

Entrain

6

the interval between the last pacing stimulus and the first return EGM

Post pacing interval

7

True or False: A PPI - TCL difference of >115msec and a VAVA response would rule out atrial tach.

True

8

Does Adenosine help in Atrial Tach?

nope

9

What kind of pacing induces Atrial tach?

Incremental Pacing
