AbstractABSTRACTSustained monomorphic ventricular tachycardia (VT) can result in hypoperfusion or devolve into more dangerous rhythms such as ventricular fibrillation. In an unstable patient with VT and a pulse, synchronized cardioversion is the first-line treatment. When the VT is refractory to standard cardioversion, the next step is to add an antiarrhythmic, such as amiodarone, that carries with it the risk of lowering blood pressure in the already hypotensive patient. Here we describe a case of double sequential synchronized cardioversion of a patient with unstable VT refractory to standard direct current cardioversion, resulting in a rapid conversion to sinus rhythm and return to hemodynamic stability. The benefit of this technique is that it may obviate the need for rapid infusion of medications, such as amiodarone, in the acute setting that may worsen hypotension in the already unstable patient.
