Case report highlights lidocaine's role in managing VT storm, suggesting effective antiarrhythmic strategies.
Effective management of VT storm during catheter ablation involves discontinuation of antiarrhythmic agents to facilitate VT induction for mapping of the critical isthmus. Lidocaine is an ideal agent since arrhythmias remain inducible after its discontinuation. In addition to providing hemodynamic support, dopamine assists by prolonging induced VT for optimal mapping.
