I am a 26 year old girl, just had an ablation done 2 weeks ago. Since then I have been experiencing palpitations when I stand up. My heart rate goes from 70 or 80 bpm to 140-150 bpm when standing up from a lying position. It's very uncomfortable and I feel extremely dizzy afterwards. Is this normal? Does this mean the ablation didn't work or that I have a different problem all together? I'm really hoping this will resolve. If anyone knows anything about this and can help please let me know!
