Summary: An evaluation of a new ECG monitor which detects and classifies ventricular extrasystoles. A device is described which is highly efficient in detecting and classifying ventricular ectopic beats. This instrument may have a significant role in patient monitoring. The system is based on analysis of a 5 electrode orthogonal system with comparison of QRS wave forms with a stored normal wave form. The design was based on a test tape derived from 26 patients and evaluated further on long recordings of 16 other patients. Results indicate that the device is highly reliable in QRS detection and in detection of ventricular ectopic beats. The problem of artefacts due mainly to patient movement is held within reasonable limits.
