Abstract

Un nouveau stimulateur cardiaque sensible au rythme et à mode double cavité, permettant de stimuler le c÷ur d'un patient, permet de suivre le rythme sinusal lorsque ce dernier est légèrement inférieur au rythme d'un capteur; en d'autres termes, en deçà d'une 'baisse de rythme maximale de fenêtre préférentielle sinusale' prédéterminée. Une stimulation au rythme du capteur s'effectue lorsque ce rythme dépasse le rythme sinusal par une valeur supérieure à ladite baisse de rythme maximale de fenêtre préférentielle sinusale. Selon le mode préféré de réalisation, une fenêtre préférentiel sinusale, qui se situe au bout de l'intervalle ventricule-oreillette, est progressivement réduite au gré de pulsations cardiaques successives par une valeur delta programmable afin d'augmenter le rythme de stimulation jusqu'à ce que ladite fenêtre atteigne une valeur nulle, dans lequel cas le stimulateur effectue une stimulation au rythme du capteur. La fenêtre préférentielle sinusale est remise à sa valeur maximale soit lorsqu'un incident auriculaire est détecté, soit à la fin d'un intervalle de vérification sinusale programmable. Le stimulateur fonctionne au rythme sinusal ou au rythme de baisse de rythme maximale, en fonction du plus rapide des deux, pendant un nombre de pulsations de rétablissement, puis augmente progressivement le rythme de stimulation jusqu'au rythme du capteur.
