[Ventricular tachycardia induced by a bent catheter electrode migrated to the pulmonary artery].
The possibility of migration of a transvenous electrode bend in the infundibulum of the pulmonary artery is a very rare complication of permanent pacing. The Authors describe the case of a patient whose transvenous electrode, positioned in the pulmonary artery 5 years after implantation, was presumably the cause of a ventricular hyperkinetic arrhythmia (VT) and of cerebral disturbances (sublipothymia, syncope). The re-position of the electrode removed the arrhythmia thus considerably improving the symptoms of the patient.
