Which medication is recommended for Ventricular Tachycardia treatment?

Lidocaine is an antiarrhythmic medication commonly used in the treatment of ventricular tachycardia, especially in cases where the patient is experiencing hemodynamic instability. It works by blocking sodium channels, which helps to stabilize the cardiac membrane and suppress abnormal electrical activity in the heart that leads to tachycardia.

Lidocaine is particularly effective for arrhythmias that originate from the ventricles, making it a preferred choice in acute situations where rapid intervention is necessary to control heart rate and restore normal rhythm. In contrast, other options, while they have their own indications, are not the first-line treatments for ventricular tachycardia. For instance, adenosine is primarily used for certain supraventricular tachycardias rather than ventricular rhythms. Calcium channel blockers can be useful in controlling heart rate in some cases but are not typically indicated for ventricular tachycardia. Digitalis primarily affects the atria and is more commonly associated with treatment for atrial fibrillation or flutter than for ventricular tachycardia. Thus, lidocaine is the most appropriate choice in this scenario.
