Final answer:
The question pertains to the initial pharmacotherapy for hemodynamically stable patients with sustained monomorphic ventricular tachycardia. Amodiaquine, sulfadoxine, and pyrimethamine are not the correct agents; instead, beta blockers, amiodarone, or lidocaine are typically used, with defibrillation as an emergency measure.
Step-by-step explanation:
Pharmacotherapy for Hemodynamically Stable (HDS) Patients with Sustained Monomorphic Ventricular Tachycardia (VT)
The first line pharmacotherapy for HDS patients presenting with sustained monomorphic VT typically involves antiarrhythmic agents. Amodiaquine, sulfadoxine, and pyrimethamine are antimalarial drugs and not typically used for VT. Instead, the approach to treating VT may include drugs such as beta blockers, amiodarone, or lidocaine, particularly in emergency settings where immediate rhythm control is necessary. Defibrillation may be indicated if the patient is unstable or does not respond to medical therapy. It is important to note that while onset of sustained ventricular contraction and respiratory paralysis signal severe events that necessitate emergency interventions such as defibrillation, they are not related to antiarrhythmic pharmacotherapy.
