Does electrophysiologic testing predict long-term efficacy of Class III antiarrhythmic drugs in patients with chronic chagasic cardiomyopathy and sustained ventricular tachycardia?
Electrophysiologic testing can predict the long-term efficacy of Class III antiarrhythmic drugs in patients with chagasic cardiomyopathy and sustained VT, potentially guiding ICD patient selection.
In patients with chagasic cardiomyopathy and sustained VT, electrophysiologic testing can predict long-term efficacy of Class III antiarrhythmic drugs. This may help in the selection of patients for implantable cardioverter defibrillator therapy.
