摘要
The stimulator is designed as a cardiac defibrillator and/or cardioverter and is fitted with a double chamber stimulator function. It contains: (i) a means for analysing the auricular and ventricular rhythms; (ii) a means for auricular and ventricular stimulation; (iii) a means (14) for de-synchronising the ventricular stimulation when the auricular rhythm exceeds an acceptable level; and (iv) a means (22) for progressive re-synchronisation in the case of a return of the auricular rhythm to an acceptable level. The re-synchronising means (22) is conditionally controlled so as only to be triggered and maintained operative if: (a) the analysing means does not detect(18, 26) any trouble with the auricular rhythm. The device is characterised in that the re-synchronising means is only triggered and maintained operative if besides condition (a): (b) the analysing means detects (20) the presence of an effective sinusal rhythm.
