I don't feel any palpitations, even when my heart rate gets up to 175 beats per minute. My doctor does not like this. He's asked me several times if I felt them before the ablation. I keep telling him no. I also don't feel pain like a "normal " person does. When my pain level gets to an 8, pain meds don't work, not even the strong stuff via iv in the er. I've always been that way with pain for as long as I can remember.
