Simultaneous Recording of Pulse Contours on Central and Peripheral Arteries with Mechano-Electronic Transducers

Abstract

The principles underlying the evaluation of the pulse wave for the investigation of cardiovascular functions are briefly set forth. Previous sphygmographic methods are reviewed and found unsuitable at low barometric pressure, extreme temps. and at conditions as given by the use of a tilt table. By application of a mechano-electronic transducer (RCA-5734), one-tube amplifer and construction of suitable adapters the simultaneous recording of arterial pulse contours on central and peripheral arteries in man is made possible even under those unfavorable conditions.
