The best way to describe the svt is that for me, I feel very jittery like I've had too much caffeine and jumped on treadmill at the same time. Other times my heart
and pauses. I have had a pretty decent cardio work-up with ekg, echo, stress test, stress echo and this Thursday I have a nuclear stress test. From everything I've read and been told by my cardio doctors, SVT, Pac's and Pvc's are totally benign if your heart is structurally normal.
