Pacemaker syndrome is an entity generated by a desynchronization between the auricular and ventricular activity during the paced ventricleVVI in patients with node disease.This syndrome can develop in moths even years after the pacemaker implant, being more frequent in elderly patients. The only treatment is to implant an auricular electrode for a synchronic atrioventricular stimulation. It presents the case of a patient diagnosed with a sinus node disease associated to long QT, for this reason it was implanted a pacemaker VVIR, few months later the patient started to have symptoms of heart failure, three years after that presented a syncope episodes showed in a Holter ECG study that reported unsustainable ventricular tachycardia episode and retrograde P waves after every ventricular stimulation sent by the pacemaker. The probability of an arrhythmic syncope was considered treated with Amiodarona. Pacemaker syndrome was diagnosed, making an improvement by a dual chamber pacemaker and all symptoms of heart failure disappeared. Syncopal event was not repeated and from the time the patient is operated on a normal functional capacity.
