Le SafeR – Microport en 10 points<\/strong>
1- Le SafeR est un mode disponible sur les stimulateurs Microport pour r\u00e9duire le
pourcentage de stimulation ventriculaire inutile
2- Le mode SafeR, AAI<=>DDD, permet une stimulation AAI avec analyse de la d\u00e9tection
ventriculaire (mode ADI)
3- Il existe un crit\u00e8re de commutation vers le mode DDD pour chaque degr\u00e9 de BAV
4- Le dispositif commute vers le mode DDD quand l\u2019intervalle PR (d\u00e9tection atriale, d\u00e9tection ventriculaire)\/AR (stimulation atriale, d\u00e9tection ventriculaire) d\u00e9passe la valeur maximale programm\u00e9e sur 6 cycles cons\u00e9cutifs (crit\u00e8re BAV1)
5- Le crit\u00e8re BAV1 peut \u00eatre programm\u00e9 sur repos + effort ou sur effort seul
6- Le dispositif commute vers le mode DDD quand 3 activit\u00e9s atriales (ondes P ou stimulations atriales) non cons\u00e9cutives sont bloqu\u00e9es sur les 12 derniers cycles (crit\u00e8re BAV2)
7- Le dispositif commute vers le mode DDD quand il d\u00e9tecte 2 activit\u00e9s atriales cons\u00e9cutives bloqu\u00e9es (crit\u00e8re BAV3)
8- Le dispositif commute vers le mode DDD quand il d\u00e9tecte une pause ventriculaire plus longue que la valeur programm\u00e9e (2, 3 ou 4 secondes)
9- Apr\u00e8s avoir commut\u00e9 vers le mode DDD, le dispositif re-commute automatiquement vers
le mode ADI apr\u00e8s 100 cycles ventriculaires stimul\u00e9s
10- Apr\u00e8s avoir commut\u00e9 vers le mode DDD, le dispositif re-commute \u00e9galement vers le
mode ADI s\u2019il d\u00e9tecte 12 ventricules spontan\u00e9s cons\u00e9cutifs (cycles AR ou PR)<\/p>
Mode AAI – SafeR<\/strong>
BASES DE FONCTIONNEMENT
Le SafeR est un mode disponible sur les stimulateurs Microport pour r\u00e9duire le pourcentage
de stimulation ventriculaire inutile.<\/p>
\u00a0Le mode SafeR, AAI<=>DDD, permet une stimulation AAI avec analyse de la d\u00e9tection ventriculaire (mode ADI). Il existe un crit\u00e8re de commutation vers le mode DDD pour chaque degr\u00e9 de BAV<\/li>
\u00a0Quand le stimulateur a commut\u00e9 vers le mode DDD, il recherche p\u00e9riodiquement le retour d\u2019une conduction spontan\u00e9e en commutant automatiquement vers le mode ADI<\/li><\/ul>
