Murmur - hypertrophic obstructive cardiomyopathy - ANSWERA systolic ejection
murmur heard along the lateral sternal border that increases with decreased preload
(i.e. Valsalva maneuver)

Murmur - aortic insufficiency - ANSWERAustin Flint murmur, a diastolic, decrescendo,
low-pitched, blowing murmur that is best heard sitting up; increases with increased
afterload (i.e. handgrip)

Murmur - aortic stenosis - ANSWERA systolic crescendo/decrescendo murmur that
radiates to the neck; increases with increased preload (i.e. squatting)

Murmur - mitral regurgitation - ANSWERA holosystolic murmur that radiates to the
axillar; increases with increased afterload (handgrip)

Classic EKG finding in atrial flutter - ANSWER"Sawtooth" p waves

Definition of unstable angina - ANSWERAngina that is new, is worsening, or occurs at
rest

Antihypertensive for a diabetic patient with proteinuria - ANSWERACEI

Beck's triad for cardiac tamponade - ANSWERHypotension, distant heart sounds, and

Appropriate diagnostic test: 50yo male with stable angina can exercise to 85% of
maximum predicted heart rate - ANSWERExercise stress treadmill with ECG

Appropriate diagnostic test: 65yo female with LBBB and severe OA has unstable angina
- ANSWERPharmacologic stress test (e.g. dobutamine echo)

on ECG or decreased BP

ECG findings suggestive of MI - ANSWERST-segment elevation (depression means
ischemia), flattened T waves, Q waves

posterior (left circumflex/oblique, RCA/marginal), septum (LAD/diagonal)
