Cardiovascular System Flashcards
(32 cards)
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
Sinus arrhythmias
Speed up with inspiration and slow with expiration
Atrial /nodal premature contraction
Early atrial/nodal beat then pause then rhythm continue
S1 greater intensity and s2 lesser
Nirmal arterial pulse
30-40mmhg
Small weak pulse causes
↑PVR
↓ SV
Larger bounding pressure causes
- ↑ Sv, ↓ PVR
↓Ccompliance
Pulses during Aortic regurgitation-
bisferiens pulse and large bounding pulse
Pulses during L.Ventricular failure-
pulus alternans and L. sided S3
Ventricular premature contraction-
regularly irregular bears, early ventricular beat then pause then rhythm continue. S1 normal s2 decreased
Atrial fib and flutter with varying av block-
no p wave ventricular rhythm(fibrillation) totally irregular and short, s1 intensity changes
