cut CN IX and X bilaterally - what is hemodynamic result? | tachycardia with hypertension |
EKG with random electrical activity without recognizable QRS complexes | ventricular fibrillation |
what can atenolol cause in high doses? | bradycardia and varying degrees of AV block |
what causes increased pulse pressure? | stiffening of arteries/ decreased arterial compliance |
what maintains a PDA? | PGE analog - alprostadil |
what artery is usually compressed in thoracic outlet syndrome? | subclavian |
what is the most common cause of sudden cardiac death in adults? | ischemic heart disease |
sudden death in heart transplant patient? | graft vascular disease |
cardiac defect associated with Fragile X? | MV prolapse and aortic root dilation |
cardiac finding in SIDS? | right ventricular hypertrophy |
endocarditis in patient with colon CA? | strep bovis |
how does cocaine cause hypertension? | blocks NE reuptake |
what substance responsible for calcified valves? | calcium phosphate |
high risk for digitoxin therapy with what metabolic problem? | hypokalemia |
decreased arterial pressure, increased systemic venous pressure, and small, quiet heart | cardiac tamponade |
rupture of ventricular wall leading to hemopericardium and cardiac tamponade, rupture of IV septum, rupture of papillary muscle can occur when post-MI? | 5-10 days |
what is the initial alteration leading to atherosclerosis? | injury to endothelial lining |
in compensated aortic coarctation, what is decreased? | vascular resistance in lower body |
drugs recommended for patients with diabetes and renal complications (e.g. hyperuricemia)? | ACE inhibitors |
bacterial endocarditis in tricuspid valve? | IVDA |
what artery is frequently damaged in knee dislocations? | popliteal |
proper initial treatment for patient with hypertrophic cardiomyopathy? | metoprolol |
anti-hypertensive causing gynecomastia? | spironolactone |
what increases upon removal of a kidney? | total peripheral resistance |
beta blockers with intrinsic sympathomimetic activity not recommended for patients with angina | acebutolol and pindolol |
patient with vasculitic symptoms, eosiniophilia, and asthma? | Churg-Strauss |
access to vertebral artery via what? | suboccipital triangle |
patients who develop digitoxin toxicity gradually during chronic therapy are often taking what type of drugs? | diuretics - hypokalemia and hypomagnesia |
increased stroke volume causes what to happen to pulse pressure? in what type of patients is this seen? | wide pulse pressure - anemic patients |
endomyocardial fibrosis with myocyte necrosis and a prominent eosinophilic infiltrate? | Loeffler endocarditis - result of direct toxicity to heart by proteins in eosinophil granules designed to kill large parasites |
what types of pericarditis may follow acute MI? | fibrinous and serofibrinous pericarditis |
what is caseous pericarditis typically due to? | TB |
these types of pericarditis can be seen in uremia, chest radiation, rheumatic fever, SLE, and following chest trauma | fibrinous and serofibrinous |
this type of pericarditis is seen when pyogenic infections involve the pericardium, e.g. after cardiothoracic surgery | purulent pericarditis |
this type of pericarditis is seen in non-infectious inflammations, e.g. rheumatic fever, lupus, scleroderma, tumors, and uremia | serous pericarditis |
amyloid deposition in the myocardium results in what type of cardiomyopathy? | restrictive - can be seen in RA and other long-standing inflammatory conditions |
what murmur is associated with a bicuspid aortic valve? | immediate diastolic murmur |
what structures have the highest ratio of wall cross-sectional area to lumen cross-sectional area? | arterioles |
what type of protein is associated with RA? | AA amyloid protein |
another name for hypertrophic cardiomyopathy? | idiopathic hypertrophic subaortic stenosis |
administration of epinephrine after what type of drug causes a decrease in BP? | alpha adrenergic antagonist, e.g. phentolamine - blockes epi's vasoconstrictive action on arterioles |
