Match each characteristic arterial pulse finding on physical examination with its most likely underlying cardiovascular pathology.
- Pulsus parvus et tardusSevere aortic stenosis
- Pulsus paradoxusCardiac tamponade
- Pulsus bisferiensHypertrophic cardiomyopathy
- Pulsus alternansSevere left ventricular failure
- Water-hammer (Corrigan) pulseSevere aortic regurgitation
Cevap
Pulsus parvus et tardus matches with Severe aortic stenosis; Pulsus paradoxus matches with Cardiac tamponade; Pulsus bisferiens matches with Hypertrophic cardiomyopathy; Pulsus alternans matches with Severe left ventricular failure; Water-hammer pulse matches with Severe aortic regurgitation.
Each arterial pulse contour directly reflects the underlying hemodynamic derangement: fixed mechanical obstruction (parvus et tardus), ventricular interdependence within a constrained space (paradoxus), dynamic outflow obstruction (bisferiens), struggling myocardial contractility (alternans), or rapid diastolic aortic runoff (water-hammer).
