Ventricular Gallup. Beginning of diastole after S2. Too
much volume - ✔✔ANSWER ✔✔-S3
Rare. Atrial Gallup. Resistance to filling. End of diastole -
✔✔ANSWER ✔✔-S4
Lateral (Circumflex): AVL- High Lateral V6 Low Lateral
,Less common/ less severe - ✔✔ANSWER ✔✔-
1/avl/V5/v6
Inferior - ✔✔ANSWER ✔✔-II/III/avf
Anterior - ✔✔ANSWER ✔✔-V1/v2/ v3/ v4
RV - ✔✔ANSWER ✔✔-V4R/ V5R
HRXSV - ✔✔ANSWER ✔✔-CO
Preload/ after load/ contractility - ✔✔ANSWER ✔✔-SV
~=70% - ✔✔ANSWER ✔✔-SVO2 from central line
Bad- it means that the tissues are not up taking O2. This
should be "used blood" so the number should be lower -
✔✔ANSWER ✔✔-Is increased SVO2 good or bad?
, Slows things down/ vagal response/ atropine blocks the
vagas nerve and speeds up HR - ✔✔ANSWER ✔✔-
Parasympathetic response
⬇️HR ⬇️contractility=⬇️BP/ ⬇️myocardial O2 demand
Used in acute coronary syndrome. Can cause HF. Look for
crackles and S3
One of the first drugs we give with angina because it
decreases myocardial O2 consumption - ✔✔ANSWER
✔✔-Betablockers
Speeds things up/ epi/ dopamine - ✔✔ANSWER ✔✔-
Sympathetic response
⬇️HR and contractility us in rapid rhythm. Don't use in
ACS. Amlodapine, dilt, nicardipine
Reduce afterload by lowering intracellular Ca+ which
inhibits smooth muscle contraction.
