title: [Regression of tachycardiomyopathy after implant of pacemaker with antitachycardial function].
abstract: A 27-year-old woman with systemic lupus erythematosus and Wolff-Parkinson-White syndrome complicated with refractory tachycardia and class III heart failure treated with pacemaker implantation was described. She had cardiomyopathy that could be due to lupus erythematosus or tachycardia-induced. Nonpharmacologic therapeutic alternative was used and a universal DDD pulse generator with selected programming was chosen. Twenty-four months follow-up showed tachycardia control and regression of symptoms of heart failure to class I as well as improvement of left ventricular function evaluated by echocardiographic method. Thus, pacemaker implant may be an useful alternative approach in patients with tachycardiomyopathy in whose other nonpharmacologic therapeutic options could not be performed.
