Match the following characteristic arterial pulse abnormalities identified on physical examination with their most likely underlying cardiovascular pathology.
- Pulsus parvus et tardus (weak and delayed pulse)Severe aortic stenosis
- Water-hammer (Corrigan) pulse (bounding pulse with rapid runoff)Severe aortic regurgitation
- Pulsus paradoxus (exaggerated drop in systolic blood pressure during inspiration)Cardiac tamponade
- Pulsus alternans (alternating strong and weak pulse beats)Severe left ventricular systolic dysfunction
Cevap
Pulsus parvus et tardus matches with Severe aortic stenosis. Water-hammer pulse matches with Severe aortic regurgitation. Pulsus paradoxus matches with Cardiac tamponade. Pulsus alternans matches with Severe left ventricular systolic dysfunction.
Each pulse abnormality has a distinct pathophysiologic mechanism linked to a specific functional or structural cardiac defect. Aortic stenosis restricts outflow (parvus et tardus), aortic regurgitation causes rapid stroke volume ejection and diastolic runoff (water-hammer), tamponade restricts left-sided filling during inspiration (paradoxus), and severe heart failure causes alternating stroke volumes (alternans).
