Cardiovascular System Flashcards
Diastolic murmur represent
Valvular heart disease→aortic regurgitation
→mitral stenosis
Systolic murmur represent
- Vascular heart disease →aortic, pul. Stenosis and hypertrophic cardiomyopathy
- Physiologic flow murmur
Murmur doing pregnancy suggests
Risk to mother/ fetus of aortic stenosis/ pulmonary hypertension
Midsystolic murmur
Blood flow across the semilunar valve
Pansystolic murmur
Regurgitant flow across AV valve
Late systolic murmur that may /may not be preceded by systolic clicks
- Mitral valve prolapse or
2. Mitral regurgitation
PMI diameter of >2.5 cm evidence of
Hypertension/ aortic stenosis→LVH
Displaced PMI >10cm lateral to midsternal line occurs in
- LVH
- ventricular dilation- MI
- HF
COPD PMI displacement
RVH→In xiphoid/epigastric area
Pathophysiology of S3 and S4
S3→ abrupt deceleration of inflow across the mitral valve (s3 gallop)
S4 →↑LV end diastolic stiffness which ↓ complianc
→ marks atrial contraction
Pressure of resting LV
<5mmHg
Opening snap OS
Mitral stenosis→maybe heard in diastole during MV opening(usually silent)
Systolic ejection sound
Pathologic condition accompanying Aortic/pulmonic valve opening
Where to search s2 splitting
Only in Left 2nd and 3rd interspace during inspiration
S1 splitting
Only at left sternal border di not vary with respiration
