The subjects considered in this article follow the logical procedures of acquisition, preprocessing, wave detection, parameter measurement, and recording of the ECG. The authors present an economic procedure for simultaneous multichannel signal acquisition, digital real-time interference elimination and drift suppression, a real-time software QRS detector, and algorithms for wave onset and termination determination. The authors also discuss fast algorithms for lengthwise and crosswise lead presentation that supports the use microdot thermal printers for signal recordings.
Duskalov et al. (1998) reported a review. Economic procedures and algorithms for simultaneous multichannel ECG signal acquisition, real-time interference elimination, and QRS detection were presented.
