PD cardio Flashcards
what type of pressure wave would be decreased stroke volume with increased peripheral resistance
parvus/weak pulse
small weak pulses
“parvus” seen in AS
what type of murmur has a large bounding pulse
AR
bisferiens pulse is seen in
AR/AS and HOCM
pulsus alternans is seen in
LVH
bigeminal pulse is seen in
mimics alternans; w premature contraction
paradoxical pulse is seen in
quiet inspiration can occur in pericardial tamponade, asthma, COPD and constrictive pericarditis**
diminished S1 is seen in
aortic regurg; blocks
accentuated S2 is seen in
mitral stenosis
the split of s1 is due to
delayed closure of the tricuspid valve
how does a physiological split of s2 occur
inspiration; delayed P2
how does pathologic splitting of S2 occur
delay split of P2 like in pulm stenosis or even early aorta so MR
wide vs fixed vs paradoxical split of S2
wide: inspiration
fixed: prolonged systole ASD
para: expiration LBBB
