What is the most posterior structure of the heart? - ANS-LA
On an EKG, what structure is always negative? - ANS-AVN
Lead I: + aVF: + - ANS-normal axis deviation
Lead I: + aVF: - - ANS-left axis deviation
Lead I: - aVF: + - ANS-right axis deviation
Pneumonic for drug classes: - ANS-So Be Pot Cautious
NYHA Class 1 - ANS-Walky talky
NYHA Class 2 - ANS-some SOB c stairs
NYHA Class 3 - ANS-no stairs
NYHA Class 4 - ANS-Can't walk due to SOB. LBBB due to remodeling qualifys.
LBBB = impulse originated from - ANS-the right
RBBB = impulse originated from - ANS-the left
With VT Mapping, look for the first focus of the V beat, not the: - ANS-direction
, LBBB, V1= - ANS-negative (car indicators)
RBBB, V1 = - ANS-positive (car indicators)
Apical VT will be negative in what leads? - ANS-II, III, aVF
RVOT VT will be positive in what leads? - ANS-II, III, aVF
Septal VT will be: - ANS-positive/negative
Precordial leads indicate anterior/posterior. If they're negative in VT: - ANS-anterior
Precordial leads indicate anterior/posterior. If they're positive in VT: - ANS-posterior
Delta waves, V1 = negative. Right/Left sided? - ANS-right
Delta waves, V1 = positive. Right/Left sided? - ANS-left
Delta waves, anterior pathway if: - ANS-II, III, aVF are positive
Delta waves, posterior pathway if: - ANS-II, III, aVF are negative
Delta waves, anterior septal pathway if: - ANS-negative in V2-V6
Delta waves, posterior septal pathway if: - ANS-positive in V2-V6
BB Reentry VT - ANS-- uses the AVN
- inverted P-waves
- ablate RBB
Reentrant VT (Scar) - ANS-- does not use AVN
- Inverted P-waves
- Adenosine will have no effect
- VA dissociation is seen
