What is the recommended treatment for stable Wide Complex Tachycardia (WCT)?

The recommended treatment for stable Wide Complex Tachycardia (WCT) typically involves the use of a Class 1b antiarrhythmic agent. In this particular case, a lidocaine bolus of 0.5 to 0.75 mg/kg is appropriate. This dosage is effective in managing ventricular arrhythmias and provides a means of stabilizing the patient's condition.

Lidocaine works by blocking sodium channels, which helps to correct the abnormal electrical activity in the heart that is characteristic of wide complex tachycardia. The dosing mentioned allows for an adequate therapeutic level while minimizing the risk of potential side effects associated with higher doses.

Other options, such as boluses of amiodarone or higher doses of lidocaine, may be considered in different contexts or specific patient scenarios but may not be the initial choice for stable WCT. Procainamide infusion can also be effective, but it is usually reserved for patients who may not respond to other treatments. In this context, the lidocaine bolus is tailored specifically for the management of stable wide complex tachycardia in a way that aligns with established protocols.
