Abstract

A method for obtaining the first derivative of the ECG electronically has been described and the curve of the first derivative displayed with the original ECG. It has been demonstrated that the first derivative emphasizes the high frequency components of the ECG and firmly establishes the fact that these are very real and significant components of the ECG. The ultimate usefulness of this method in electrocardiographic diagnosis remains to be determined.
