Automated family classification in ambulatory arrhythmia monitoring.

A system to analyze ambulatory arrhythmia monitoring has been developed which is highly specific and sensitive. It has been used to process seven tapes per day (comprising clinical caseload and data for antiarrhythmic drug studies) in a clinical environment. This system has also been used to investigate two-channel ambulatory electrocardiograms, where the additional information provided is expected to improve the ability to deal with artifact and the problem of isoelectric premature ventricular contractions. A correlation of QRS complexes with operator-selected decisions has also been tested. While time-consuming, it is reliable and amenable to optimization solutions.
