| Question | Answer |
|---|---|
| when to use thallium v stress treadmill to assess angina | when can't see ST changes well, incl abnl baseline EKG, LVH, MVP, WPW, LBB, pacemaker, young women (high false +), quinidine, procainamide, dig |
| contraindications to stress testing | USA, AoS, severe COPD, acute isch changes on ECG, severe uncontrolled HTN (and Ao dissection) |
| what's syndrome X | exertional angina, incl exercise testing and nuclear imaging showing myo isch, but no stenosis on cath |
| name non selective b blocker | propanolol, nadolol timolol, pindolol |
| name cardiac selective b blockers | esmolol (ultra fast), metoprolol, atenolol |
| 2 alternatives to ASA | ticlopidine (watch for neutropenia)and clopidogrel |
| s/p PTCA what meds | ASA + ticlopidine/clopidogrel + GIIb/IIIa (abciximab, tirofiban, eptifibatide) |
| pathoophysiol and 5 elements of metabolic syn X | insulin resistance due to obesity; incrsd Chol&TG, impaired glu tol, DM, HTN, incrsd uric |
| contraindications to full dose heparin in AMI | HEAPS=HTN (>190/110), Endocarditis, Activ bleeding or hemorrhagic diathesis, Purpura, Surgery (recent neuro or ocular) |
| what parts of the heart do ea cor artery supply | RCA=P LV, RV and RA, SA and AV node; LCA=A LV, A 2/3 of interventricular septum; LCx=L LV |
| EKG of PE | S in I, Q in III, inverted T in III [think SQT in I,II, III] |
| MC cause in hospital mortality s/p MI, overall mortality s/p MI | CHF, arrhythmia |
| how tx 2nd degree type II block s/p MI | if anterior MI emergent temp pacemaker, if inferior MI IV atropine (if unsuccessful then pacemaker) |
| which are more likely to rupture, ventricular psudoaneur or aneur | pseudoaneur |
| how tx angina after tPA | angioplasty or bypass |
| what is amiloride? Triamterene? Bumetanide? Metolazone? Indapamide? | amiloride and triamterene are both K+ sparing like spironolactone, but don't cause gynecomastia; bumetanide is a loop; metolazone and indapamide are thiazide |
| what is the CHADS2 score | risk of stroke w non rheum A Fib: CHF, HTN, 75yo, h/o stroke/TIA (counts as 2, rest count as 1) |
| what are 2 common dig related conduction problems | paroxysmal atrial tachy w 2:1 block, A Fib w PVC and slow ventricular rate |
| 2 congenital QT syndromes, genetics, tx | AR Jervell-Lange-Nielsen w congenital deafness, AD=Romano Ward; symptomatic tx w b blocker (QT will remain long) |
| which infarct area assoc w AV block | diaphragmatic |
| Lenerge dz | MC cause of 3rd degree block, senile fibrosis of conduction system |
| when see large v wave on JVP | TR (and MR) |
| when see incrsd a waves | pulHTN and RHF |
| when see cannon a waves in JVP | arrhythmias ie 3rd degree block when atria pushing ag closed TV, also V Tach or A Flutter |
| rapid y descent can be seen in 3 dz | constrictive pericarditis, restrictive CM, TR |
| describe how/why S2 splits | when inspire more blood in RV and PV stays open longer (AV then PV) |
| what leads to wide split S2 | R vol overload, pulHTN, also MR |
| what leads reverse splitting S2 | AS, HOCM (AV stays open longer)--maybe also pul HTN--not sure |
| 3 CAD risk equivalents | DM, PVD, AAA |
| how tell when to put on 1 HTN med, 2 med | HTNI gets 1 med, HTNII needs 2 (both w lifestyle changes) |
| which BP med use in AA | diuretic (they are usu salt sensitive) |
| what causes an anterior infarct? Posterior? Lateral? Inferior? | LAD, PDA, LAD or LCx, RCA |
| which artery and infarct do you need to watch for RV failure | RCA and inferior |
| which are anterior leads? Lateral? Inferior? Septal? | anterior=I, V1-6; inferior=II, III, aVF, lateral=I, aVL, V5, V6; septal=V1,V2 |
| definition of BBB | QRS>0.12 |
| nml axis | positive I and aVF |
| LAD by I and aVF | I=+, aVF=- |
| RAD by I and aVF leads | I=-, aVF=- or + |
| in considering arrhythmias, when is a pt considered unstable | SBP <90, AMS, CP, SOB |
| LBBB v RBB on ECG | *W*i*LL*ia*M* *Ma*RR*o*W* W in QRS in V1-2 and M in V3-V6=LBBB; M in QRS in V1-2 and W in V3-V6=RBBB; |
| dx of LVH | amplititude of R in aVL + S in V3>24males or 20females |
| dx of RVH | RAD + R wave in V1>7 |
| dx RAE | P in II>2.5 |
| dx LAE | biphasic P in V1 |
| 3 features of WPW on ECG | short PR, delta wave, wide QRS |
| list of CAD risks used to calculate when to treat lipids | CAD equiv=DM, PVD, AAA; CAD risks: current smoking, HTN, DM, HDL <35 (>60 is negative), age m>45, f<55; male (don't count if already counting age), fam hx of MI in m<55 in f<65 |
| what ECG change is specific for RV infarct | ST elevation in R sided V4 RV4 |
| MC presenting sympt for HOCM, AS, MVP, long QT, myocarditis | HOCM=dyspnea, AS=dyspnea, MVP=CP, long QT=syncope, myocarditis=dyspnea& fatigue |
| MC arrhythmia s/p MI | V Fib |
| MC cause cardiogenic shock | s/p AMI |
| MC cause of death s/p endocarditis | CHF |
| general tx for regurg L heart lesions | decrs afterload w ACEI |
| pt h/o MI and MR, what Rx take them off | b blocker (incrses preload) |
