RESUMO
Mulher de 27 anos de idade, portadora de lupus eritematoso sistêmico e síndrome de Wolff-Parkinson-White, com episódios freqüentes de taquicardia paroxística supraventricular por reentrada atrioventricular refratários ao uso de medicaçäo anti-arrítmica e que desenvolveu insuficiência cardíaca (classe funcional III da NYHA). Como opçäo terapêutica näo-farmacológica foi implantado marcapasso com funçäo antitaquicardia tendo sido observada diminuiçäo do número e duraçäo dos episódios e conseqüente regressäo da insuficiência cardíaca para a classe I. O acompanhamento ecocardiográfico revelou melhora no desempenho ventricular esquerdo. Embora nos relatos da literatura somente säo encontradas descriçöes de regressäo de taquicardiomiopatia após secçäo cirúrgica ou ablaçäo transcateter, o emprego de marcapasso com modo de funçäo antitaquicardia pode beneficiar pacientes que näo podem ou se recusam ser submetidos a tais procedimentos
ABSTRACT
A 27-year-old woman with systemic lupas 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 choosen. 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 usefull alternative approach in patients with tachycardiomyopathy in whose other nonpharmacologic therapeutic options could not be performed.
