title: [Validity and limits of invasive pharmacological tests in the treatment of malignant ventricular hyperkinetic arrhythmias].
abstract: Programmed stimulation can now be safely performed for the evaluation of therapy for recurrent ventricular tachyarrhythmia. The initiation of ventricular tachycardia appears closely related to its actual spontaneous clinical occurrence. Serial electrophysiologic studies can be performed and are effective in prospectively evaluating the response to antiarrhythmic drugs. The efficacy of therapy based on the results of programmed stimulation appears to be good. On the other hand, Amiodarone can be effective in the chronic treatment as well as in patients with ineffective acute drug test.
