ABSTRACT:
An active implantable medical device comprising circuits for measuring trans-thoracic impedance and delivering an impedance signal varying with respiratory activity of a patient. A signal representative of the respiratory activity of the patient is delivered starting from the impedance signal, and circuits for diagnosing respiratory disorder analyze variations of the respiratory signal on a plurality of successive cycles to detect there a profile of predetermined variation in relation to a given respiratory disorder. The device also includes circuits for automatically controlling respiratory cycles with artifacts, able to identify in the impedance signal a jump of static impedance, and/or to identify in a respiratory cycle or in a sequence of respiratory cycles a predetermined singularity representative of a cycle with artifact.
