Active implantable medical device e.g. pacemaker, for diagnosing e.g. sleep apnea syndrome, has sensor measuring endocardiac acceleration whose parameters are determined and provide value for delivering alert signal of apnea or hypopnoea
The device has a sensor measuring variations of an endocardiac acceleration (EA) of a patient and integrated to a head of an endocardial lead placed at a base of a ventricle. The sensor has a distal electrode receiving traces of an electrogram during three consecutive cardiac cycles. An appearance of a sleep apnea or hypopnoea is detected and the acceleration is received. Function parameters (PEAI, PEAII) of the received acceleration are determined and an alert signal of the sleep apnea or the hypopnoea is conditionally delivered based on a value obtained by the parameters.
