Match each specific cardiovascular pathology with its most characteristic arterial pulse or hemodynamic physical examination finding.
- Chronic severe aortic regurgitationRapidly rising bounding pulse with a quick collapse
- Hypertrophic obstructive cardiomyopathyBifid carotid pulse with a brisk initial upstroke followed by a mid-systolic dip
- Cardiac tamponadeExaggerated decrease in systolic blood pressure during inspiration (> 10 mm Hg)
- Severe calcific aortic stenosisDiminished amplitude and delayed peak of the carotid upstroke
Answer
Chronic severe aortic regurgitation matches with rapidly rising bounding pulse; Hypertrophic obstructive cardiomyopathy matches with bifid carotid pulse; Cardiac tamponade matches with exaggerated decrease in systolic blood pressure during inspiration; Severe calcific aortic stenosis matches with diminished and delayed carotid upstroke.
Each cardiovascular pathology produces distinct hemodynamic alterations that manifest as specific physical examination findings. Aortic regurgitation causes a widened pulse pressure and bounding pulse due to rapid forward and backward flow. Hypertrophic obstructive cardiomyopathy creates a bifid pulse due to dynamic outflow obstruction. Cardiac tamponade exaggerates ventricular interdependence, leading to pulsus paradoxus. Severe aortic stenosis creates a fixed outflow obstruction, resulting in a weak and delayed pulse.
