Question

What is the indication for the use of magnesium in cardiac arrest?

- Pulseless v tac - associated torsades de pointes
- V tach associated with a normal QT interval
- Shock refectory ventricular fibrillation
- Shock refractory monomorphic ventricular tachycardia

Answer 1

Magnesium is indicated for the treatment of certain cardiac arrhythmias in cardiac arrest.

Step-by-step explanation:

Indication for the Use of Magnesium in Cardiac Arrest

Magnesium is indicated for the treatment of certain cardiac arrhythmias that are associated with a risk of sudden cardiac death. It is commonly used in the following situations:

1. Pulseless ventricular tachycardia (v tach) associated with torsades de pointes.
2. Ventricular tachycardia (v tach) associated with a normal QT interval.
3. Shock refractory ventricular fibrillation.
4. Shock refractory monomorphic ventricular tachycardia.

In these cases, magnesium can help stabilize the heart rhythm and improve the chances of successful resuscitation.
