Cardiac Normals Flashcards
Pulse pressure
SBP-DBP 40-60
ABI
ankle BP/brachial BP
> 0.9
Pulse pressure
40-60 mmHg
Low or narrow indicated hypovolemia
High or wide indicates sepsis or shock
RCA occlusion/lesion
ii, iii, aVF(inferior)
V1, V2 (post LV)
V3R, V4R (RV)
LDA occlusion/lesion
V1,V2,V3,V4(anterior LV or LM)
CX occlusion or lesion
V5,V6, i, AVL (lateral LV)
Inferior MI
RCA occlusion
ii, iii, aVF
Conduction issues and systolic murmur
2’1, 3’, SSS, SB
RV infarct
RCA occlusion, get r sd ekg,
Pt may have JVD, Inc CVP, clear lung,
Give ivf and Inotropes
NO preload reducers, no nitro, careful with bb
Anterior MI
LAD occlusion
V1-V4
Conduction issues and HF
2’2, RBBB
systolic murmur
Retro bleed
Back pain, BP suddenly drops
Give 250ml bolus, 0.5mg iv atropine if needed, check CBC, act, aptt know normals inr and platelets, get consents for blood, 1:1 for every point below 8 of hgb, give ffp and platelets if massive trans, call IR
Acute decomp systolic dysfunction
Lv fills ok, pump bad
Dilated, hormones cause vent remodeling
S/s:MVR, pulm edema low BP, high SVR,
Tx: reduce meds that contribute (levo etc) give ace I, diuretic, vaso dilators, positive inotropes
No bb or ccbs
Tamponade
From pericarditis, heart surg, trauma
S/s: restless, poor LOC, narrow PP, Becks triad(low BP, increased JVD, muffled heart), low CO, high wedge, high CVP, pulses paradoxes
Tx pericardialcentesis, drain
Aneurism
From HTN, smoking, obese, infections
S/s: abdomen pulsations, abd, scapula, low back pain, NV, shock, hoarse, dysphasia, dyspnea, sudden tearing pain chest back neck
Tx: CT/US, If <5cm TEE(abdomen), TTE(thoracic), beta blockers to slow growth
If >5cm surg repair, treat HTN and HR with labetalol or lopressor
Dissection if suddenly Inc cp back pain, weakness, low uo, diff cuff pressure in both arms
