51 yr old brother had pacemaker implanted after 6 fainting-flatlining episodes. Mri/ct scan showed brain/heart not the problem. Why is this happening

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? ...Read more

How can I have an MRI scan with claustrophobia?

Ask your provider: While open MRI can be an option, the magnet is much weaker than closed mri. This means the picture quality is not as good, like the difference between an inexpensive camera and a professional one. For some areas of the body, the open is okay. For others (spine in my practice) the higher quality is critical. Sedation can be used to deal with claustrophobia. Your provider can guide you. ...Read more
