Is It Normal To Shake And Have Increased Heart Rate With SVT Attack?

I have been diagnosed with AVNRT SVT, but I was researching. With the attacks after them I shake crazily almost like i'm having a seizure (I've had seizure from the time i was born until I was about 8 years old). I wore an event monitor which is what they caught my attacks on. My heart rate gets, most of the time, 150 or above. I'm just kind of worried I've maybe been misdiagnosed, or I could just be over thinking it but it was called to my attention when I had an attack with my grandparents around. I am scheduled for a cardiac oblation the beginning of February. Yet my doctors haven't tested me for anything else they've just ran an echo, and many EKG's. Is it normal to shake with an SVT attack?
