Abstract
We have developed a microprocessor-based analyzer for processing the high-frequency electrocardiogram. It has a signal band-width of 500 Hz, five times that of the standard clinical ECG. The device is programmed to isolate QRS complexes, to compute their first derivatives, and to dilate the time base so that the high frequency ECG´s and their derivatives can be recorded on a restricted-bandwidth hard copy device such as a strip chart recorder or ECG machine. Also, the analyzer interfaces directly to a laboratory computer system for additional signal processing.
