Correlation of Simultaneously Recorded Electrokymograms and Pressure Pulses of Human Heart and Great Vessels

Abstract

In order to define more precisely meaningful points on ventricular and great vessel electrokymograms, intraluminal and intracavitary pressures have been simultaneously recorded. Electrokymograms of the superior vena cava and the pulmonary artery show remarkable constancy of time relationships with simultaneously recorded intraluminal pressure curves. The ventricular electrokymogram is more difficult to define and its limitations are discussed.
