Abstract

Enhancement of marking symbols indicative of abnormal ECG beats displayed on a CRT storage tube may be effected by periodic revivification. An arrhythmia computer is utilized to detect and classify the abnormal beats-and their location is marked by a symbol generated by a character generating circuit. Visual enhancement is effectuated by periodically resetting the character generator in accordance with the desired refresh repetition rate.
