Clinical Experience with a System Based on Analysis of R-R Interval Patterns

Clinical experience with computer based analysis of long-term ECG recordings has been gained from about 6000 patients. The system is intended for analysis of recordings from patients presenting with symptoms possibly caused by cardiac arrhythmias. In such patients, elaborate analysis and display of R-R interval patterns has been regarded as more important than classification of QRS morphologies. With the aid of a comprehensive, yet easily assimilated computer report of rhythm and efficient routines for retrieval and display of computer indicated episodes we have been able to limit the mean operator’s time to about 10 minutes for a 24-hour recording.
