Abstract
Detecting a lead fracture in an active implantable medical device for pacing, resynchronization and/or defibrillation of the heart. This device senses the heart rhythm through an endocardial lead comprising at least one endocardial electrode collecting the depolarization potentials, and detecting the myocardium contractions through an endocardial acceleration sensor. The device detects an incipient or total lead fracture by correlating the signals representative of successive ventricular and/or atrial depolarizations (P, R) with the signals representative of successive acceleration peaks (e.g., PEA I). In the case of a lack of correlation, a signal of suspicion of lead fracture is delivered, notably to generate an alarm signal through recording of markers in a memory of the device readable by an external programmer, RF transmission and/or production of an audible signal.
