To the editor: We read with interest the report by Westveer and associates (1) of amiodarone-induced ventricular tachycardia 5 days after the start of therapy. Aggravation of ventricular tachyarrhythmias by class I antiarrhythmic compounds is not uncommon, but the electrophysiologic effects of amiodarone are somewhat different. The worsening of ventricular tachyarrhythmias is rare despite the fact that the QTc interval invariably lengthens as part of the beneficial drug action during chronic amiodarone therapy. Amiodarone may aggravate arrhythmias, but when this appears to be the case, one must determine whether the unexpected arrhythmia resulted from primary drug action (excessive dose or
