Previous studies using an aortic electromagnetic flowmeter at surgery or the intra-aortic catheter pressure gradient technique have indicated a characteristic phasic flow pattern of rapid, early systolic ejection and reduced, late systolic ejection in individuals with hypertrophic subaortic stenosis. A transcutaneous Doppler velocity probe was used in the study of 10 individuals with proved hypertrophic subaortic stenosis to determine if a pattern of flow similar to that described by other techniques could be recorded and to evaluate the possible application of this external method for the diagnosis of hypertrophic subaortic stenosis. Hoppler velocity recordings of carotid flow were obtained simultaneously
