Abstract

A third generation adaptive new ST Rule that provides a more accurate ST detection mechanism for next generation cardiac pacemakers, ICDs, drug pumps, monitors or other devices. The new ST Rule is a rule which, when met, may control delivery or withholding of therapy. The new ST Rule includes an adaptive onset criteria. An expected range of RR-intervals is calculated based on a trimmed means and a metric of RR variability to be derived over a preceding series of RR intervals. The expected range is updated adaptively after ventricular events. Preferably, the expected interval range is not adapted to curing on 1:1 rhythms. The activity of the adaptive onset criteria provided by the new ST Rule is further augmented by available atrial information. Specifically, patent codes indicative of gradual rate changes in normal sinus rhythm, if they persist, results in a new ST Rule being made. Patent codes inconsistent with sinus tachycardia, for example, those indicating a non 1:1 rhythm or rapid rate change associated with sudden onset of VT will result in the new ST Rule not being met. Thus, distinctions are met between various tachyarrhythmias to provide appropriate therapies and treat the identified tachyarrhythmias.
