case_images: The study began at 19 : 25 and ended at 19 : 34; it yielded 36 images in 6 series together with the initial topogram (Figure 1).
case_images: Therapy history: episode 460. Detection of ventricular fibrillation on November 5, 2008 at 19 : 32, coincident with the CT scan exam. Diverted therapy due to reconfirmation analysis.

case_images: Electrograms of episode 460. Oversensing due to artifacts that start capacitors charge and provoke ventricular pacing inhibition.

case_images: The oversensing provokes the charge of the capacitors and at the same time causes significant pauses due to inhibition of ventricular pacing (Figure 3).
