Cardiology Intro Flashcards
when is it best to shock someone? (cardioversion)
during a heart beat
where do inferior heart attacks originate from?
right coronary artery
atrial flutter beats a minute?
50 beats a minute
Paroxysmal supraventricle tachycardia
QRS narrow (going through normal conduction system), coming from above AV node
no flutter
starts and stops
younger individual
ventricular tachycardia
start in bottom chamber
QRS wide
where will edema be in signs of right heart failure
legs and sacrum
liver
spleen
ascites
valve closure sound S1
mitral and tricuspid components
- mitral is louder
- enhanced by positive inotropic states
- reduced by closure end diastolic leaflets
valve closure Sound S2
aortic and pulmonic
what does a split S2 mean?
pulmonic delay due to increased ejection time with increased filling
when is S2 louder?
hypertension
pulmonary and systemic
fixed splitting of S2
hear during expiration (no split should be heard)
- RBBB
- left to right shunt
- pulmonary outflow tract obstruction
what murmur causes elderly to pass out?
crescendo/decrescendo at the RSB
paradoxical splitting S2
splitting normally occurs during inspiration (not during expiration)
paradoxical is opposite: are heard on expiration
b/c of: LBBB, aortic stenosis (prolonged ejection), patent ductus (increased LV stroke voluem)
APTM
Aortic, pulmonary, tricuspid, mitral
diastolic murmur at RSB
aortic valve
-aortic insufficiency
