[Indications for implantable automatic defibrillators].

The automatic implantable defibrillator is an effective therapeutic tool for palliative treatment of severe ventricular arrhythmias. There is a significant reduction in sudden death in implanted patients. However, reliable data on the long term global mortality is not yet available. The indications are difficult to define apart from special cases. A large number of factors has to be taken into consideration: the clinical presentation of the arrhythmia, and the different medical and non-medical therapeutic options. At present, it is not possible to arrive at a consensus on the indications of automatic implantable defibrillators. Therefore, it is illusory to construct decisional algorithms. The authors suggest therapeutic orientations rather than strict clinical indications, based on recommendations published by the working groups on cardiac arrhythmias and pacing of the European Society of Cardiology and on their own personal experience.
