Final answer:
Lidocaine is indicated for stable wide complex tachycardias like ventricular tachycardia (VT). Examples include ventricular tachycardia without hemodynamic compromise, monomorphic ventricular tachycardia, and sustained polymorphic ventricular tachycardia.
Step-by-step explanation:
Lidocaine is indicated for the treatment of stable wide complex tachycardias like ventricular tachycardia (VT), where the heart beats abnormally fast due to abnormal electrical signals. Lidocaine works by stabilizing the electrical activity in the heart and reducing the risk of life-threatening arrhythmias.
Examples of stable wide complex tachycardias include ventricular tachycardia without hemodynamic compromise, monomorphic ventricular tachycardia, and sustained polymorphic ventricular tachycardia.
It is important to note that lidocaine may not be the first-line treatment for stable wide complex tachycardias, and it should be administered under appropriate medical supervision.
