Studies on High Amplitude Electrocardiogram—Relation between the high amplitude ECG and the usual ECG

　To observe minimal electrocardiographic trac-ings, we have cultivated the high amplitude electrocardiograph it raises five times the ampli-tude. These high amplitude electrocardiogram are compared with the usual electrocardiograms.
