Abstract:
A new and original non-invasive method of indirectly determining the elasticity of the arterial wall in a subject which has not been mentioned in the medical literature up to present comprising the steps of:a) making use of a patient's left external carotid artery as a â€œcentral arteryâ€  and the patient's left dorsalis pedis as a â€œperipheral arteryâ€ ; b) attaching a metallic plate on a pick-up microphone of a high frequency oscillograph; c) placing the metallic plate directly on the patient's skin over the left external carotid artery and the left dorsalis pedis; d) recording arterial pulses of the left external carotid and the left dorsalis pedis arteries using the oscillograph for a period of time; and e) getting a difference between the arterial pulses to measure a time interval between the instant that the pulse is recorded from the â€œcentral arteryâ€  and the instant that the same pulse is recorded from the â€œperipheral arteryâ€ .
