This : This sounds like an episode of low blood sugar. You need to have a medical evaluation by your doctor as soon as possible. You will need a history, physical, blood tests, and ekg. Hopefully with all of the above, a diagnosis can be made and treatment started. In the meantime if this occurs drink a glass of juice or eat a piece of fruit and monitor for improvement. Best of luck.

Bradycardia: Symptomatic bradycardia can be serious and i would recommend going to an urgent care clinic or er for evaluation asap.
