Amiodarone and lidocaine in emergency care are used to do what?

Explanation:
Antiarrhythmic medications are used to restore or maintain a normal heart rhythm during emergencies. Amiodarone and lidocaine work by changing how electrical impulses move through the heart and by increasing the time before heart cells can fire again. This helps stop or prevent dangerous fast rhythms, especially ventricular tachycardia or ventricular fibrillation that can occur in cardiac arrest or other emergencies. They aren’t used to lower blood pressure, slow breathing, or directly treat chest pain—those issues are addressed with other drugs and therapies.
