What is Beck’s Triad? What do these symptoms indicate?
- Hypotension
- Increased JVP (distended neck veins)
- Distant, muffled heart sounds
Indicates acute cardiac tamponade!
What is Kussmaul’s sign? What does it indicate?
Increase in JVP on inspiration instead of a normal decrease.
Seen in constrictive pericarditis, restrictive cardiomyopathies, RA or RA tumors.
What is pulsus paradoxus? What does that indicate?
Decrease in systolic BP by >10mmHg during inspiration.
Indicates cardiac tamponade, asthma, obstructive sleep apnea, pericarditis.
How are each of the three types of hyponatremia treated?
Hypovolemic hyponatremia – saline injection
Euvolemic and Hypervolemic hyponatremia – Vaptams may be used (ADH receptor antagonists)
What valvular defect presents with a holosystolic murmur?
Mitral regurgitation (intensity of murmur constant through systole)
What valvular defect presents with a midsystolic murmur (crescendo-decrescendo)?
Aortic stenosis
What valvular defect presents with a blowing diastolic murmur?
Aortic regurgitation
What valvular defect presents with a holosystolic machine like murmur?
PDA
What is the general MOA for fibrates?
Activate PPAR-alpha to induce HDL synthesis.
Activate LPL to clear more triglycerides from the blood.

What are the indications of spironolactone?
Primary or secondary hyperaldosteronism
Cirrhosis of the liver
Could be used with K+ wasting diuretics to prevent hypokalemia
