Latest Patents

Dirk Mussig holds a patent for an implantable cardiac device designed for adaptive ventricular rate smoothing during atrial fibrillation. This device operates by switching to a non-atrial synchronized pacing mode when atrial fibrillation is detected. The ventricular escape interval (VEI) is modulated beat-by-beat around a physiological interval zone (PIZ), which is determined by the pre-arrhythmia ventricular rate or the output of a rate-responsive sensor. The VEI remains unchanged if the preceding ventricular event is sensed and its RR interval is within the PIZ. If the preceding RR interval exceeds the upper limit of the PIZ, the VEI is decreased toward a lower interval threshold. Conversely, if the preceding RR interval is shorter than the upper limit, the VEI is increased toward an upper interval threshold. This adaptive mechanism ensures a rapid recovery of deviant RR intervals toward the PIZ, thereby reducing the frequency of high-rate ventricular paces after a ventricular sense with a very short coupling interval.
