Inappropriate implantable cardioverter defibrillator discharge following consumption of a dietary weight loss supplement.
This report describes the clinical course of a 40-year-old female who experienced repetitive ICD firing after consuming Metabolife 356, a multicomponent dietary weight loss supplement. Following the initiation of Metabolife 356, the patient experienced four shocks over a 3 day period with two 30 J shocks being delivered sequentially. Interrogation of the device revealed atrial tachycardia with 1:1 AV conduction at a rate of 240 beats/min. Metabolife 356 was discontinued and the dosage of sotalol was increased to 120 mg twice daily without recurrence of ICD discharge.
