What is the first line of medication for pulseless ventricular tachycardia?

When a patient is in pulseless ventricular tachycardia, the priority is to restore circulation as quickly as possible. Defibrillation is the primary treatment to reset the rhythm, but medications are used to support the patient during ongoing CPR and improve the chances of return of spontaneous circulation. Epinephrine is given first because it constricts blood vessels, which raises the aortic diastolic pressure during CPR and improves blood flow to the heart and brain. This perfusion boost helps make defibrillation more likely to succeed and supports ROSC. The standard approach is to administer epinephrine early in the arrest, typically 1 mg IV/IO every 3–5 minutes during ongoing CPR. If the rhythm remains nonperfusing after initial shocks and epinephrine, an antiarrhythmic like amiodarone is considered next (lidocaine is an alternative if amiodarone isn’t available). Atropine, on the other hand, is not effective for pulseless VT and isn’t used for this rhythm. So, the first-line medication in this scenario is epinephrine because it enhances perfusion during CPR and improves the likelihood of achieving ROSC, setting the stage for successful rhythm restoration.
