A Comparison of Electrokymography and Roentgenkymography in the Study of Myocardial Infarction

The authors present two cases of myocardial infarction to demonstrate that electrokymography is superior to roentgenkymography as a method for detecting localized areas of myocardial damage. This superiority is based principally on greater ease of exploration of the ventricular pulsations, clearer delineation of the kymographic curve as a result of greater magnification, and more accurate analysis of the phases of the cardiac cycle by simultaneous recording and integration with other graphic tracings.
