Was just recently diagnosed with vasovagal instability. My primary basically mentioned Dysautonomia approx 2 years ago. I also have SVT and have suffered with it since childhood.
Do any of you have both Dysautonomia and heart arrhythmias? I just experienced a really bad episode of SVT - worse one I think I've ever had... my heart rate went up to 210 bpm. My cardiologist went through me with every test under the sun; stress (both treadmill and nuclear die), EKG, echo, and holter monitor... all were clear and normal.
