The Pathfinder High-Speed E.C.G. Analyser. Use in detection of arrhythmias during oral surgery.

Automatic analysis of arrhythmias from a tape recorded electrocardiogram (e.c.g.) is described, and its application to the detection and comparison of these during halothane and enflurane anesthesia is discussed. The results confirm that the use of enflurane during oral surgery produces much greater cardiac stability than the use of halothane.
