1. An implantable medical device comprising:
an implantable defibrillator configured to generate an electrical defibrillation signal;
an implantable electrode connected to the implantable defibrillator by a lead and configured to deliver the electrical defibrillation signal to a patient;
an implantable sensor configured to detect mechanical vibrations by the heart of the patient and to provide a detection signal based on the detected mechanical vibrations; and
a controller configured to analyze the detection signal to determine at least one parameter characterizing the mechanical vibrations and to provide a defibrillation operation of the implantable defibrillator, the defibrillation operation based only on the determined parameters characterizing the mechanical vibrations.
