Interpreting EMGs Flashcards
PPI-TCL < 115 ms
AVRT
PPI-TCL > 115 ms
AVNRT
A and V will line up
AVNRT
There will be an AH jump
AVNRT
Delta waves on surface ECG
AVRT
VT with LBBB where is it coming from?
RV
VT with RBBB where is it coming from?
LV

Delta waves V2-V6 +
Posterior septal
Delta waves V2-V6 -
Anterior Septal
A spike that is not followed by an V
AV block
V spike that is not followed by an A spike
VA block
Block Below the AV node
A but no V
Block above the AV node
A but no H or V
Pacing spike with no atrial deflection to follow
AERP
Pacing in ventricle, s2 would show a pacing spike with no V spike to follow
VERP
pacing spike with A spike with no H to V spike
AVNERP
Delta wave goes away and the AV fusion will seperate
AP Block
AV fusion is seen
indications of an AP conduction
A and V line up on EGM
AVNRT
In flutter if the sequence is from proximal to distal is it CW or CCW?
CCW
How would sinus node reentry appear on EGM?
The Tachy beat would look identical to the sinus beat
In flutter if the sequence if from distal to proximal is it CW or CCW?
CW
VAV response suggests what?
AVNRT or AVRT
