  • Publication number: 20100152597
    Abstract: What is described is an implantable telemetric device for measuring the electromechanical parameters of the heart, characterized in that it comprises a single sensor (5) and corresponding processing means for detecting data relating to both the rotation of the heart and the mechanical vibrations which correspond to the first heart sound (FHS) and the second heart sound (SHS), and in that it comprises means which use these data for diagnostic and/or therapeutic purposes. Said sensor (5) is of the type which can generate a broadband electrical signal proportional to the rotation rate (RotR) of the heart and proportional to said mechanical vibrations corresponding to the heart sounds. Means are provided for processing this RotR signal, for deriving therefrom the functions relating to the rotation of the heart (?RotRdt) and to mechanical vibrations (d(RotR)/dt) corresponding to the said heart sounds (FHS, SHS) and for detecting data derived from combination of the said functions (e.g.

  • Patent number: 7664547
    Abstract: An active implantable medical device with biventricular pacing and automatic optimization of pacing configuration. The device collects and analyzes an endocardial acceleration signal (EA), and searches for an optimal pacing configuration based upon a performance index derived from at least one value relating to one and/or the other of the two endocardial acceleration peaks (PEA I, PEA II) over a given heart cycle. Optimization search operates through a scanning of a parameter, e.g., atrio-ventricular delay, and calculation of the surface area underneath the characteristic of the peak amplitude as a function of the scanned parameter (atrioventricular delay).

  • Patent number: 6493585
    Abstract: Electrodes can generate electrical stimulation pulses at least one first intensity level and at least one second intensity level. The first and second intensity levels are above and below a given stimulation threshold, respectively. The synchronous or asynchronous delivery of second-level pulses enables the conduction of the atrioventricular node to be modulated by electrotonic effect, for example, to reduce ventricular frequency in the event of atrial fibrillation.

  • Patent number: 6477418
    Abstract: An implantable dual-chamber pacemaker system has a means for automatic beat-to-beat adjustment of the maximum allowable variation (MAV) of the sensed atrial rate (AR) as a function of the sympatho-vagal balance, switching from an atrial tracking mode of operation (e.g., DDD or DDD(R)) to a non atrial tracking mode (e.g., VDI or VDI(R)) when either an arrhythmic tachycardic rate, exceeding the MAV, or a sinus tachycardic rate, exceeding the maximum tracking atrial rate (MTAR), is detected. The pacemaker provides logic means for continuously determining the atrial rate variation (&Dgr;AR) and the MAV. The MAV defines the upper limit for the &Dgr;AR above which tracking is not allowed, discriminating between physiological rate variations and arrhythmic variations. The pacemaker system can return to an atrial tracking mode of operation if the AR remains under a defined rate for a defined number of cycles.

  • Publication number: 20020123674
    Abstract: The invention relates to an implantable device for therapeutic and diagnostic purposes, which is capable to detect the physical properties of the pulmonary tissue which depend from its density and their variations caused by a pathologic condition of the heart (heart failure, ischemia, arrhythmia), using one or more intrapulmonary catheters, provided with sensors, inserted in branches of the pulmonary artery. The catheters provided with sensors preferably use as sensors electrodes and the detected physical property, which depends by the density of the pulmonary tissue, is preferably the bioelectric impedance of the explored portion of lung. The same electrodes can be also used for monitoring of an electrocardiogram, without artefacts and interferences.
