Abstract
The roentgen electrokymograph utilizes significant fluctuations in the fluoroscopic roentgen beam, to produce graphic records of such physiologic phenomena as the pumping action of the heart and the capillary pulse of the lung parenchyma. This new device consists of a clinical fluoroscope, a 931-A (or equivalent) multiplier phototube with its necessary power supply, a selective filter to absorb the alternating current ripple in the roentgen beam while passing the significant current fluctuations that are to be recorded. Some form of recording galvanometer, and a means for the simultaneous registration of some such time-reference curve as the carotid sphygmogram, an oscillogram of the heart sounds, or an electrocardiogram. The apparatus is described in sufficient detail so that the reader may build it for himself. Records are shown, of ventricular motion, including a case of myo-cardial infarct, and of aortic and pulmonary artery pulsations, including cases of right and left bundle branch block. A basis for interpretation of electrokymograms is outlined.Keywords
