Abstract
The carotid pulse has been recorded by external means in 33 patients with proved aortic stenosis (subvalvular in 4), 164 patients with other disorders of the heart and circulation, and 75 healthy subjects. In every patient with valvular stenosis and 3 of the 4 with subvalvular obstruction the diagnosis could be made from the pulse tracing: some correlation was found between the pulse contour and the severity of both obstruction and associated regurgitation. Criteria have been established for the recognition of aortic stenosis from the external carotid pulse tracing.
