Relationship between the pressure and diameter of the carotid artery in humans.
The purpose of this study was to examine the assumption of similarity between pressure and diameter-change waveforms in humans. We measured carotid arterial pressure and diameter change, simultaneously, in six patients with heart disease. In all patients, the carotid arterial pressure-diameter relationship could, in practice, be regarded as being linear.
