| Popis: | Le systems de detection de ľactivite auriculaire present dans les stimulaleurs actuels VDD ou DDD ne permet pas de faire avec certitude to distinction entre ľactivit? aurieulaire normale et retrograde. Il apparait done necessaire de mettre au point un systeme efficace de detection et de prevention des tachycardies induites par les stimulateurs, qui ne limitera pas les benefices hemodynamiques apportes par ces appareils. Clinical evaluation performed on an external prototype of a programmabie VDD pacemaker showed a high risk of induction of pacemaker-mediated tachycardia. In these tests tachycardia was observed following magnet removal, premature atrial and ventricular complexes, myopotential oversensing, detection of electri-cal interference and other events. The high risk and poor predictability of pacemaker-mediated tachycardia suggest that VDD (or DDD) pacemakers should provide automatic means to control this kind of tachycardia without undue loss of the hemodynamic benefits which can be provided by these units. |
