    • Ventricular Fibrillation (VF) or Pulseless Ventricular Tachycardia (VT):
      • Immediate defibrillation.
      • Follow with CPR if defibrillation is unsuccessful.
      • Administer epinephrine and antiarrhythmic medications as per ACLS guidelines.
    • Asystole or Pulseless Electrical Activity (PEA):
      • Begin CPR immediately.
      • Administer epinephrine.
      • Identify and treat reversible causes (H’s and T’s).
    • Bradycardia with a pulse (severe, symptomatic):
      • Administer atropine.
      • If atropine is ineffective, consider transcutaneous pacing, dopamine infusion, or epinephrine infusion.
    • Supraventricular Tachycardia (SVT) or other narrow complex tachycardias (if causing hemodynamic instability):
      • Synchronized cardioversion.
      • If stable but symptomatic, consider vagal maneuvers or adenosine.
