Cardiovascular Flashcards
right ventricle
-occupies most of the anterior cardiac surface and is easily accessible to palpation
s1
- usually louder than s2 at apex
- diminished in first-degree heart block
s2
- usually louder than s1 at base
- diminished in aortic stenosis
carotid artery
- palpation during auscultation is invaluable aide in timing of sound or murmur
- carotid upstroke always occurs in systole immediately after s1, sounds or murmurs coinciding with upstroke are systolic
- sounds or murmurs occurring after completion of upstroke are diastolic
apical impulse
- Represents brief early pulsation of left ventricle as it moves anteriorly during contraction and touches chest wall
- left ventricular area
s2
- inspiratory splitting caused by closure of aortic, then pulmonic valves
- 2 componets A2 and P2 caused by closure of aortic and pulmonic valves
- during inspiration, the closure of the aortic valve and closure of pulmonic valve separate slightlym and this may be heard as 2 audible components, instead of a single sound
murmur at cardic apex
mitral valve- sounds are usually heard best at and aroudn cardiac apex
orthopnea
dyspnes that occurs when patient is lying down and improves when patient sits up. if positive may indicate CHF
Normal BP
<120/80
Prehypertension
120-139/80-89
Stage 1 htn
140-159/90-99
Stage 2 htn
> 160/100
diabetes or kidney disease
< 130/80
carotid vs jugular pulse
Carotid is palpable; jugular venous is rarely palpable. Carotid upstroke normally brisk, but may be delayed and decreased in aortic stenosis or bounding as in aortic insufficiency
Elevated jugular venous pressure
- JVP reflects pressure in right atrium
- causes include
- -constrictive pericarditis
- -right-side heart failure
- -tricuspid stenosis
- -superior vena cava syndrome
cause for increase in amplitude of apical impulse
- hyperthyroidism
- severe anemia
- pressure overload of left ventricle (i.e., aortic stenosis)
- volume overload of left ventricle (mitral regurgitation)
