Shockable
LEAD II · 25 mm/sVT (mono)

Characteristics

Rate
150–250 bpm

Regular
QRS
Wide (> 120 ms), uniform morphology

Common causes

  • Ischemia / prior MI
  • Cardiomyopathy
  • Electrolyte disturbance

ACLS treatment

  1. 1Pulseless VT → Cardiac Arrest algorithm: defibrillate 200 J biphasic, CPR, epi 1 mg q3–5 min, amiodarone 300 mg then 150 mg.
  2. 2Stable VT with pulse: amiodarone 150 mg over 10 min, or procainamide.
  3. 3Unstable VT with pulse: synchronized cardioversion 100 J biphasic.
