Description and Analysis of the Hewlett-Packard 78220 Arrhythmia Monitoring System.

Abstract

The Hewlett-Packard (HP) 78220 Arrhythmia Monitoring System is ventricular-oriented and detects the most significant ventricular contractions (PVCs) of Lead II electrocardiograms (ECGs). The HP monitoring software consists of a number of relocatable program modules. The program modules are divided into three main categories. The first is called system initialization, the second is real time processing, and the third is background processing. The real time portion includes the AZTEC transformation which is applied to the input waveform and records only the changes in the waveform that succeed some predetermined threshold to achieve a tremendous data reduction.
