What medication should be given to a stable patient with SVT as seen on an EKG?

• A. Adenosine
• B. Lidocaine
• C. Digoxin
• D. Procainamide

Answer: (A)

Adenosine is the preferred medication for the management of stable patients experiencing supraventricular tachycardia (SVT), particularly when there is a clear indication based on the EKG findings. Adenosine works rapidly to interrupt the reentrant pathways in the heart and can effectively restore a normal sinus rhythm within seconds. Its pharmacokinetics allow for very quick action; it is administered as a rapid intravenous bolus, causing an immediate but transient block in conduction through the atrioventricular (AV) node. When considering treatment for SVT, it's essential to note that while other medications like lidocaine and procainamide may play roles in managing different types of tachycardias, they are not first-line agents for stable SVT scenarios. Lidocaine is primarily utilized for ventricular arrhythmias and may not effectively address reentrant SVT problems. Procainamide is more appropriate for ventricular tachycardia and certain atrial arrhythmias but is not indicated as a first-line agent for stable SVT. Digoxin can slow the heart rate but is generally more indicated for rate control in atrial fibrillation and may take longer to have an effect, making it less suitable in acute management of SVT compared to ad
