Hello,
Thank you for posting your query at DoctorSpring.com
Yes, neuro cadiogenic syncope or vasovagal syncope can occur at intervals of six months or one year.
The room precipitating factors for syncope include fasting, exhaustion, fear, dehydration, severe pain, etc.
The diagnosis of syncope can be confirmed by doing HUTT test (head up tilt test).
I hope it helps.
Best wishes,
Dr. Sudhir Kumar MD (Medicine), DM (Neurology)

Patient replied :
I have already had 2 head up tilt's. Both negative. Valsalva maneuver negative. Could this be a migraine variant without headache pain and no visual disturbances? EKG and ECHO normal. I am positive for classic migraine. When I have these episodes I do not have pain before or after . Does this matter?
Patient replied :
Does the migraine variant have a name? I have tried many preventatives already. A normal Echo and ekg does not rule out cardiac as if it isn't recorded while it is happening then it can't be diagnosed. That is what an ILP is for. I was trying to find out the name of a migraine variant that would cause a sudden drop in Blood Pressure (no increase in Pulse) without headache pain. Is there such a disorder? What is it called? Where can I find info?
