Abstract
A system used by a technician for evaluating a Holter ECG tape having a signal representing a series of waveforms thereon and for generating a report reflecting the evaluation. A tape reader generates from the ECG tape an analog signal representative of the ECG waveforms recorded on the tape. An A/D converter converts the analog signal into a digital signal. A computer including a data bus, a memory, a processor controls the operation of the system. A display displays waveforms representing the ECG. A storage device is connected to the data bus. A direct memory access device moves the digital signals from the converter to the memory for storing the digital signal in the storage device. The converter provides at least a 12 bit a digital signal corresponding to the analog signal and includes means for converting the 12 bit digital signal to an 8 bit digital signal.
