Final answer:
The treatment of choice for torsades de pointes is to correct the underlying cause, stabilize the heart rhythm, and prevent future episodes.
Step-by-step explanation:
The treatment of choice for torsades de pointes is to correct the underlying cause, if possible, and to stabilize the heart rhythm. One commonly used medication is intravenous magnesium sulfate, which helps to normalize the electrical activity of the heart. In addition to magnesium sulfate, other medications such as lidocaine or procainamide may also be used.
If the torsades de pointes is life-threatening or persistent, immediate intervention is required. This may involve electrical cardioversion, which is a controlled electric shock to restore a normal heart rhythm. In some cases, a temporary pacemaker may be inserted to regulate the heart's electrical activity.
Prevention and long-term management of torsades de pointes may involve identifying and avoiding triggers such as certain medications or electrolyte imbalances, as well as optimizing the treatment of any underlying conditions that may be contributing to the arrhythmia.
