29
Patient presenting with right-sided heart failure following pace-maker implantation is due to
Tricuspid regurgitation | - due to lead placement causing direct leaflet damage or inadequate leaflet coaptation
30
Effects of digoxin toxicity
nausea, vomiting, diarrhea, vision changes (yellow/green), and arrhythmias
31
Isolated systolic hypertension
systolic >140 and diastolic <90 - seen in old men - due to increased stiffness and decreased elasticity in aortic and arterial walls

47
MOA and SE of digoxin
slows the conduction through the SA and AV nodes by inhibiting the Na+/K+ ATPases of the cardiac myocytes SE: abdominal pain, yellowing vision, heart block. *give immune Fab antibody
48
Restrictive cardiomyopathy with fibrosis and prominent eosinophilic infiltrate
Loffler syndrome
49
Debakey Classification
Type I involves the ascending aorta, arch, and descending thoracic aorta. Type II is confined to the ascending aorta. Type IIIa involves the descending thoracic aorta distal to the left subclavian artery and proximal to the celiac artery. Type IIIb dissection involves the thoracic and abdominal aorta distal to the left subclavian artery.
50
Most common cause of aortic dissection
hypertension
51
Hypertensive crisis tx
nitroprusside, nicardipine, clevidipine, labetalol, and fenoldopam
52
Medication CI in WPW and A-fib
digoxin - blocks the AV node and shortens the pathway needed for depolarization down the accessory pathway increasing the risk of v-fib
53
chest pain with diaphoresis. ECG findings of ST elevation in leads V1-V3 and ST depression in leads II, III and aVF
Anteroseptal infact (see reciprocal changes in II, III and aVF)
54
Prinzmetal angina
transient narrowing of the coronary vessels by the contraction of the smooth muscle in the vessel - EKG: transient ST elevations - tx: CCB, sublingual NTG to relieve vasospasm
55
EKG in hypercalcemia
shortened QT interval
56
EKG in hypomagnesemia
nonspecific T wave changes and a prolonged QT interval. As the deficit progresses, Torsades de pointes, a polymorphic ventricular tachycardia, may result - common in alcoholics
57
posterior MI EKG
a posterior STEMI presents as ST depression (reciprocal ST elevation) and R-waves (reciprocal Q-waves) in leads V1-V3.
58
Endocarditis and conduction abnormality on EKG
perivalvular abscess
59
Pt with recent URI develops increasing SOB. CXR shows enlarged cardiac silhouette and she has clear lung sounds on PE with jugular vein distension

63
meds shown to prolong survival in left ventricle dysfunction
ACEi, ARBs, BB, mineralcorticoid receptor antagonist (aldosterone), hydralazine and nitrates in AAs
64
Why do you give sodium bicarb in TCA overdose
increases serum pH and sodium level, alleviating the cardio-depressant action on sodium channels
65
Triptans and ergot derivatives are avoided in patients with
CAD - can cause vasospasm
66
Pt complains of transient, rapid, painless monocular vision loss. States it appears as if a curtain is being drawn down over his visual field
Amaurosis fugax - retinal ischemia due to atherosclerotic emboli from internal carotid - get duplex US of neck
67
medication contraindicated in prinzmetal angina
propanolol - can exacerbate vasospasm
68
left main artery is occluded greater than or equal to 50%
bypass surgery
69
Brugada syndrome
- most common cause of sudden death among young men of Asian descent without known underlying cardiac disease (possible mutation with Na channels in myocytes) - die in their 40s - die from ventricular tachycardia (VT)/ventricular fibrillation. - persistent ST elevations in the V1–V3 leads with a right bundle branch block appearance, with or without terminal S waves in the lateral leads - tx: ICD
70
indications for valve replacement in endocarditis
1. prosthetic valve endocarditis especially when associated with valve dysfunction or Staphylococcus aureus or Gram-negative rod bacteremia; 2. uncontrolled infection leading to conduction abnormalities, periannular suppuration, and fistula despite appropriate antibiotic treatment for at least 1 week; 3. repeated systemic embolizations despite appropriate antibiotic treatment; 4. severe valvular disease resulting in refractory congestive heart failure.
