ANGULO ELERS, Carlos Manuel; REYES SANCHEZ, Raúl Ernesto  e  GARCIA SALAS, Enrique Antonio. Pacemaker syndrome due to inadequate selection in the stimulation way. MEDISAN [online]. 2016, vol.20, n.10, pp. 2287-2293. ISSN 1029-3019.

The case report of a 52 years patient is presented that had a ventricular unicameral permanent pacemaker for 9 years, due to a symptomatic dysfunction of the synusal nodule. The pacemaker had dead battery and the generator was substituted. A month after the change the patient went to the Arrhytmias and Pacemaker specialized service at "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, due to symptoms of easy tireness, dyspnea, dizziness and fainting fits; surface electrocardiograms were indicated that showed a ventriculoauricular retrograde conduction and pseudofusions. Taking into account the clinical features and the electrocardiographic findings, a pacemaker syndrome was diagnosed and it was decided to implant an auricular electrode and vary the stimulation modality to that of double camera, as effective therapy for it. The symptoms disappeared and the patient had a favorable clinical course when he was discharged from the hospital institution
