Not sure.: Pacemakers not implanted without very specific indication. Mri/ct scanning is not expected to demonstrate any abnormality for fainting or flatlining. Ask electrophysiologist and interventional cardiologist who implanted the device. Your brother should no longer have fainting after implant. Continued symptoms suggest another cause....Seizure? Psychiatric?

Cardioinhibition: Your question is far to specific to answer here. A few possibilities include (the most common) something called cardioinhibition. Other more rare possibilities include conduction system disease and very dangerous heart rhythms which would require a defibrillator rather than a pacemaker.
