BIOTRONIK Announces the First Implantation of the PHYLAX AV ICD in the United States.LAKE OSWEGO Oswego, city, United StatesOswego (ŏswē`gō), city (1990 pop. 19,195), seat of Oswego co., N central N.Y., on Lake Ontario and the Oswego River; founded 1722, inc. as a city 1848. The largest U.S. port on Lake Ontario, it is a port of entry and a northern terminus of the New York State Canal System., Ore.--(BUSINESS WIRE)--Feb. 8, 1999--BIOTRONIK, Inc. announced today the first implantation of the PHYLAX AV av avoirdupois; see avoirdupois weight, under weight.AV, A-V atrioventricular; arteriovenous., a dual-chamber implantable cardioverter automatic implantable cardioverter-defibrillator an implantable device that detects sustained ventricular tachycardia atrial tachycardia a rapid cardiac rate, usually 160–190 per minute, originating from an atrial locus. atrioventricular (AV) junctional tachycardia , atrioventricular (AV) nodal tachycardia junctional t. atrioventricular nodal reentrant tachycardia that resulting from reentry in or around the atrioventricular node; it may be antidromic, or fibrillation and terminates it by a shock or shocks delivered directly to the atrium.car·di·o·ver·ter (kär defibrillator (ICD) on February 5, 1999. The PHYLAX AV ICD was implanted in a patient who survived a recent Cardiac Sudden Death episode as a result of developing ventricular fibrillation, a condition in which the heart beats dangerously fast, which could be fatal to the patient. The PHYLAX AV introduces a new era of intelligent AV discrimination with SMART Detection(TM). SMART Detection(TM) provides a unique algorithm to differentiate heart rhythms by comparing activity in the atria and ventricles to ascertain the origin of the heart rhythm and determine the appropriate therapy. This algorithm results in increased specificity without compromising sensitivity. The SMART Detection(TM) evaluates each individual event, taking into account not only the atrial and ventricular rhythms, but also the relationship between the two rhythms. The PHYLAX AV is a dual-chamber ICD capable of treating dangerous heart rhythms by providing antitachycardia pacing (high rate pacing) or defibrillation therapy to restore the normal rhythm of the heart. In addition to the SMART Detection(TM) Algorithm, the PHYLAX AV provides dual-chamber pacing with Dynamic Hysteresis Hysteresis Used to characterize a lagging effect. Firms may fail to enter markets that appear attractive, or firms that are once invested in a market may persist in operating at a loss. The effect is characteristic of investments with high entry and exit costs along with high uncertainty. and Dynamic AV Delay to optimize hemodynamics hemodynamics /he·mo·dy·nam·ics/ (-di-nam´iks) the study of the movements of blood and of the forces concerned.hemodynam´iche·mo·dy·nam·ics (h  .

Tachycardia therapies include 30 joules J of delivered energy and multiple antitachycardia treatment schemes, which is delivered upon detection of the fast heart rhythm. The Phylax AV is implanted using the TMS 1000, Tachyarrhythmia Monitoring System, the first complete implant and follow-up analyzer and programmer. 1.
