Ventricular Tachycardia Associated with SibutramineTreatment

pp. 541-543

Abstract

The prevalence of obesity is increasing in the last decades. The importance of the body image makes people use adjuvants to diet to reduce weight more quickly and effectively. Sibutramine is a drug that inhibits serotonin and norepinephrine reuptake. The stimulation of the sympathetic nervous system produces adverse effects on the cardiovascular system that have been reported by diverse monitoring agencies.

We describe the case of a woman who presented monomorphic ventricular tachycardia after initiating treatment with sibutramine. The complementary tests showed no evidence of structural heart disease and the electrophysiology study did not induce VT. The patient did not present arrhythmias after the drug was discontinued.
