[Polymorphous ventricular tachycardia: the implant of a permanent atrial pacemaker and long-term follow-up in a case].
Polymorphous ventricular tachycardia is a malignant arrhythmia associated to reversible conditions such as electrolyte imbalance, drug action, ischemia or Q-T prolongation. It is usually self limited ending with the correction of the triggering factor. We report a 70-year-old woman with a myocardial infarction who developed polymorphous ventricular tachycardia which persisted after several days. A temporary atrial pacing electrode was used effectively to control the arrhythmia, and permanent implantation was finally required. Eighteen months after discharge, the pacemaker function is normal and the arrhythmia has not recurred.
