A Pocket Electrocardiograph Carried by Patient for Observation of Various Cardiac Attacks

Abstract

In order to make accurate diagnosis of cardiac attacks, such as angina pectoris or transient arrhythmia, it is necessary to obtain electrocardiograms during the episodes. To make this possible, we have developed a pocket electrocardiograph that is small, light, easy-to-operate, features minimal recording distortion and is inexpensive.
The efficiency of this system in making clinical diagnosis has been proved by its application to 100 cases of varying cardiac attacks. There were several interesting cases among these in which the findings obtained by application of our system were unexpected.
