Question: In reviewing literature addressing treatment and management of tachyarrhythmias, I’ve encountered several articles stating that lidocaine and amiodarone are contraindicated for treatment of Torsades de Pointes as they could prolong the QT interval and worsen the situation. However, our medical directives for ventricular tachycardia make no mention of this contraindication and make no distinction in the management of VT vs TdP. Recognizing that lidocaine as a Class I antiarrythmic would be worse for the patient than amiodarone (Class III) and that amiodarone is the preferred drug in our protocols for VTach, should we nonetheless be concerned with the use of either of these in managing TdP? Thanks for providing the forum in which to ask and share with colleagues.
