I would def get a second opinion
I will definitely do that. I've had so many lately and they are like grandmal seizures from what my family who have witnessed them say.
I would get a 2nd opinion... I hay myclonic seizures but mine only last a few seconds and are usually increased in frequency by stress... my doc has had me conntact their office every time I have one because I have had 2 in the past that lasted a few min but the hospital could find no trace of what caused them. id let ur doc know about them and find out what they wanna do.
Just try to take it easy. I would think your doctors would be concerned about the heartrate being so high. Maybe get a second opinion.
