Pulses bc I hate this mf

small, weak pulse

large, bounding pulse

bisferiens pulse

pulsus alternans

bigeminal pulse

pulsus paradoxus

diminished pulse pressure, slow upstroke, peak prolonged

small, weak pulse

decreased SV, increased PVR

causes of a small, weak pulse

increased pulse pressure, rapid rise and fall with brief peak

large, bounding pulse

increased SV, decreases PVR, increases vascular stiffness/resistance

causes of a large, bounding pulse

increased arterial pressure with double systolic peak

bisferiens pulse

HOCM, AR, AR+AS

causes of bisferiens pulse

regular, but force of pulse alternates with weak and strong

pulsus alternans

severe left ventricular dysfunction

what is pulsus alternans indicative of?

normal beat alternating with premature contractures dt diminished SV of premature contracture so amplitude varies

bigeminal pulse

greater than normal drop in systolic pressure during inspiration, amplitude varies with respirations

pulsus paradoxus

pericardial tamponade, constrictive pericarditis, obstructive pulmonary disease

what is pulsus paradoxus found in?
