N2 - The external blood pressure pulse, recorded on a non-contact basis using the method of laser Doppler vibrometry (LDV), has been shown to be a rich source of information regarding cardiac and vascular dynamics. Considerable attention has been directed specifically to the pulse from the neck, overlying the carotid artery, which is of special interest because the carotid pulse is highly similar to the central aortic pressure pulse. The findings presented here are consistent with an interpretation of the signal at the neck as originating in the carotid artery. A detailed mapping study involving a 35 point matrix over the right neck disclosed a focal zone of maximal signal amplitude, with a course consistent with the tract of the underlying carotid. Appreciable individual differences in the 22 examinees were disclosed, particularly at lower sites. In addition to confirming a local source for the LDV carotid pulse, the data highlight the importance of accurate targeting considerations.
