Im a 20yr old female so had an ablation aug 1st for SVT. Since then I have been SVT free! Woohoo!
But I have also been diagnosed with IST since then, and have been struggling to manage. I was diagnosed 4 days ago, and was prescribed Ivabradine for it with promising results. I have also been tested for POTS & I do not have that. My symptoms are constant lightheadedness, racing heart rate with minimal exertion and fatigue. However I do have a normal heart rate while resting but it does skyrocket with minimal exertion. I have symptoms regardless of my heart rate(symptoms are more intense with higher HR) but my electrophysiologist believes it is from my prolonged IST that has caused some damage to my system. Any thoughts? Anyone with IST? Is it normal to have symptoms with normal HR? Anyone on IVabradine?
