Which medication is recommended for Ventricular Tachycardia treatment?

• A. Adenosine
• B. Lidocaine
• C. Calcium Channel Blocker
• D. Digitalis

Answer: (B)

Lidocaine is the recommended medication for the treatment of ventricular tachycardia (VT) due to its properties as a class 1b antiarrhythmic agent. It works by stabilizing the cardiac membrane and decreasing the automaticity of ectopic pacemakers, which is key in managing VT. Lidocaine is particularly effective in situations where the VT is associated with ischemic myocardial tissue, as it can help to restore normal rhythm by reducing the excitability of the myocardium.

In contrast, other options like adenosine are primarily used for paroxysmal supraventricular tachycardia (SVT) rather than VT. Calcium channel blockers and digitalis may be useful in certain arrhythmias, but they are not as effective as lidocaine in terminating ventricular tachycardia, especially in emergency settings. Therefore, the use of lidocaine streams in the management protocols specifically targeting ventricular tachycardia.
