Implantable cardioverter-defibrillator (ICD) electrogram anti-tachycardia pacing for monomorphic ventricular tachycardia (VT)

Stored intracardiac electrogram from an ICD showing the development of monomorphic ventricular tachycardia, which is successfully terminated by a burst of anti-tachycardia pacing delivered by the ICD. This tachycardia is monomorphic VT, but is labeled VF by the device because it was detected in the VF zone due to the rapid rate.
