I was laying down and I felt like my head had an electrical current running through it, then I passed out. This happened 3 times. You should also know I have heart issues, an AICD and pacemaker, ejection fraction 30%. Is this a symptom of something I should be concerned over? I have passed out before and they believe it was orthostatic hypotension. I have been under a lot of stress lately.
I think you may be having this manifestation due to heart problems. Low ejection fraction and malfunction of pacemaker may cause transient hypoperfusion of brain presenting as loss of consciousness. If seizure was also present with unconsciousness then it may be stoked Adam syn Chat Doctor.  You need to consult your cardiologist for checking pacemaker. An EEG of brain and neuroimaging may be done. Hoping you recover early.
