Modifications of the original ARGUS/H system for analysis of Holter tapes have continued to focus on attempts to reduce the human review and verification time required by the system. A series of algorithms which enable the computer to automatically label true-PVCs (Premature Ventricular Contractions) which are preceded and followed by a normal QRS complex ( ″isolated-PVCs″ ) has been developed. The automatic labeling algorithms utilize not only available ARGUS morphological data, but also include analysis of contextual timing information and of coupling intervals of various PVC clusters. The algorithms have been evaluated on 24 Holter recordings of 8-12 hours in length. The machine was able to correctly identify 94. 8% of all isolated true-PVCs with a false positive rate of less than 0. 4%. In addition, the new algorithms detected twice as many missed-PVCs as did the original system.
