Résumé
In this short communication we briefly describe a 69-year-old man with dilated cardiomyopathy and an implantable cardioverter defibrillator who suffered a prolonged episode of palpitations. The interrogation of the device revealed an episode of ventricular tachycardia successfully treated with antitachycardia pacing. However, just before ventricular tachycardia termination, atrial fibrillation ensued. This specific proarrhythmic effect of antitachycardia pacing is concisely discussed. Retrograde conduction from the ventricles to the atria causing increased atrial pressures and mechano-electrical feedback, in the presence of a vulnerable atrial substrate, seems to be the most plausible mechanism. <
