1

define pulseless electrical activity

organized rhythm on cardiac monitoring without a measurable blood pressure or palpable pulse in a cardiac arrest patient

2

clinical symptoms of supravalvlar aortic stenosis

- unequal carotid pulses
- differential blood pressure in upper extremities
- palpable thrill in suprasternal notch

3

systolic anterior motion of mitral valve in patients who have

hypertrophic obstructive cardiomyopathy

4

supravalvular aortic stenosis have angina during exercise, why?

increased myocardial oxygen demand

5

Beck's triad

hypotension
distended neck veins
muffled heart sound

6

Decreased cardiac contractility is seen in patients who have

systolic heart failure

7

Beck's triad is diagnostic for what? what causes these symptoms

cardiac tamponade
- shift of interventricular septum toward left ventricular cavity

8

what causes the patient's dyspnea and weakness in cardiac tamponade

decreased left ventricular preload

9

what are pathologicial causes of exterional syncope

- v tachs
- outflow obstruction

10

when do you see prominent capillary pulsations in the fingertips or nail beds

aortic regurgitation

11

history of recent upper respiratory tract infection followed by sudden onset of cardiac failure in otherwise healthy person suggests

dilated cardiomyopathy, secondary to acute viral myocarditis

12

what is performed in patients with cardiac tamponade for diagnosis and management

echocardiography

13

what is pulmonary capillary wedge pressure in PE

low to normal

14

single photon emission CT scan of heart at rest and during stress shows what? treatment

can show ischemia
- anti platelet

15

treatment for Wolff-Parkinson-White syndrome who develop atrial fibrillation with RVR

cardioversion
Procainamide

16

diagnosis for intermittent coronary artery vasospasm? treatment?

prinzmetal angina
- calcium channel blocker ( diltiazem, amlodipine)

17

PE finding for mesenteric ischemia

severe preumbilical abdominal pain

18

prolonged 'PR' interval

first degree heart block

19

'F' waves

atrial flutter

20

treatment for first degree AV block

observation

21

captopril radionuclide renal scan can diagnose

renovascular disease or renal artery stenosis

22

irregularly irregular, narrow complex tachycardia, fine fibrillatory waves

a fib.

23

when do you defibrillate a patient

ventricular fibrillation
pulseless ventricular tachycardia

24

treatment for chronic venous insufficiency

leg elevation
exercise
compression threapy

25

PE findings for chronic venous insufficiency

varicose veins
skin discoloration
medial skin ulceration

26

most dangerous complication of Marfan syndrome

aortic dissection

27

complication of aortic dissection

aortic regurgitation: early diastolic murmur

28

pulsus parvus et tardus ? seen in

arterial pulse with decreased amplitude and delayed peak,
- aortic stenosis

29

treatment for uremic pericarditis

hemodialysis

30

high voltage QRS complexes, lateral St segment depression, lateral T wave diagnosis

left ventricular hypertrophy
