Patent number: 8214036Abstract: An active implantable medical device that is able to perform an atrial capture test. The device includes circuits for delivering atrial stimulation pulses, and testing atrial capture, namely to detect the occurrence of an atrial contraction after the application of an atrial stimulation pulse. An acceleration sensor is used to deliver an EA signal representative of the movements produced by the contractions of the atrial cavity. The EA signal is analyzed to recognize and isolate in this EA signal a component EA4 corresponding to the fourth endocardiac acceleration peak (PEA4) associated with the atrial activity. The presence or absence of this component EA4 is used to define the atrial capture or loss of capture. The signal analysis preferably quantifies an EA parameter (T, T+D), such as the energy of the EA signal within analysis time windows, each having duration D, of successive analysis (W1 . . . Wn) triggered after the atrial stimulation (P) and ending before a ventricular detection or stimulation.Type: GrantFiled: November 18, 2009Date of Patent: July 3, 2012Assignee: Sorin CRM S.A.S.Inventor: Cyrille Casset

Patent number: 8195281Abstract: An active medical device able to discriminate between tachycardias of ventricular origin and of supra-ventricular origin. Two distinct temporal components (UnipV, BipV) are obtained corresponding to two EGM signals of ventricular electrograms. The diagnosis operates in at least two-dimensional space to determine, from the variations of one temporal component as a function of the other temporal component, a 2D characteristic representative of a heart beat and, this, for a reference beat collected in Sinus Rhythm (SR) in the absence of tachycardia episodes, and for a heart beat in Tachycardia. The discrimination of the tachycardia type, VT or SVT, is then realized by a classifier operating a comparison of the two current and reference 2D characteristics.Type: GrantFiled: March 27, 2009Date of Patent: June 5, 2012Assignee: Sorin CRM S.A.S.Inventors: Renzo Dal Molin, Christine Henry, Jinan El Arab, Paola Bouchet, Rémi Dubois, Gérard Dreyfus

Patent number: 8195293Abstract: Sensing ventricular noise artifacts in an active implantable medical device for pacing, resynchronization and/or defibrillation of the heart. This device concerns sensing heart rhythm through an endocardial electrode collecting the depolarization potentials, and detecting the myocardium contractions through an endocardial acceleration sensor. The device searches for ventricular noise artifacts (X, Y) by correlating the signals representative of successive ventricular and atrial depolarizations (P, R) with the signals representative of successive acceleration peaks (PEA I). In case of a lack of correlation, a signal of suspicion of ventricular noise is delivered, which temporarily modifies the sensing sensitivity (S) of the sensing circuit.Type: GrantFiled: May 18, 2007Date of Patent: June 5, 2012Assignee: Sorin CRM S.A.SInventors: Marcel Limousin, Elodie Vincent

Patent number: 8190247Abstract: Method for detecting cardiac events, e.g., Atrial Fibrillation (AF) or termination of AF. Based on analysis of the instability observed in heart rate, caused by irregular conduction from the atrium during AF. Change in heart interval is monitored on beat-to-beat basis to recognize instability that indicates presence of AF or Atrial Flutter. A packet of a number of consecutive intervals is evaluated, whether the length of an interval is stable compared with the length of the preceding interval, or whether the length of the subsequent interval has changed. After detection of an instability, instability counter is incremented. The result of the stability test for a packet of intervals is represented by the value of the instability counter. Depending upon whether or not an AF already declared, (indicated by AF status flag), different “X-out-of-Y” criterion are applied. AF status flag set/cleared when declaring AF/termination of AF.Type: GrantFiled: October 14, 2009Date of Patent: May 29, 2012Assignee: Biotronik CRM Patent AGInventors: Indra B. Nigam, Dirk Muessig
