What is the treatment for stable Polymorphic Ventricular Tachycardia (PVT)?

Stable Polymorphic Ventricular Tachycardia (PVT), often associated with conditions such as Torsades de Pointes, is best treated with Magnesium sulfate. Administering magnesium can help stabilize the cardiac membrane and slow down the heart rate. Magnesium is particularly essential in addressing the underlying electrolyte disturbances that can lead to the development of this arrhythmia.

The other options don't specifically target the treatment of stable PVT. While Amiodarone is commonly used for various tachyarrhythmias, it is primarily indicated for stable monomorphic VT and not for Polymorphic VT when the patient is stable. Sodium bicarbonate can be used in cases of metabolic acidosis or certain drug overdoses but is not a first-line treatment for PVT. Cardioversion is typically indicated for unstable tachycardia or when the patient is hemodynamically compromised, rather than for stable cases. These treatments highlight the importance of addressing the specific characteristics of the arrhythmia and the patient's overall condition.
