I want to buy a toyota hybrid vehicle, however, I have dual deep brain stimulators that are controlled by pacemaker like devices in my chest. The chest devices send an electrical current to metal rods placed thru by brain to control Parkinson\'s disease movement disorder. I recent;y test drove one of these vehicles at a local dealer and the next day felt that my devices were turned off. My question is, how can I find out if the hybrid techonology is not compatable with my divices? Also if this does affect my devices would it also affect heart pacemakers?
