It sounds like you should get checked out. However, driving is prob not the best idea if you are concerned about passing out or impaired vision. Can you get someone to take you to the hospital? If not, call an ambulance. My mate is an ambo and they would much rather come to see you at home, than have to fix you and others if you have a car accidento on the way. Too many accidents caused by people having heart issues and driving themselves to hospital.

have you tried nurse on call?

take care,
