Hi. Here is some background info about me... I am 21/male, do not drink or smoke. When I was 19 I was diagnosed with SVT. Since then I have been on Atenlol (sp?) to control it, and it's been working mostly. Ever since then I have been easily freaked out about random "off beats." My doc says this is normal and that I am healthy. Last night I woke up and for several seconds I was unable to move my arms, legs, or head. Opening my eyes was difficult. In my dream my body went numb and I was unable to move. When I woke up I struggled to move my limbs but could not, I tried to call out, but berely a whisper... Should I be concerned? I wonder if even though I was awake and concious that I was still in a mode of sleep which is why I could not move or speak?
