I 've had a low pulse (low 50's) since my ablation, but my initially low BP suddenly went very high & meds not apparently effective now. Yesterday afternoon, my heart suddenly started palpitating but did not stop as it has been doing and my HR went up to 170-200 BPM. I then got some chest pain & went to local hospital. I was kept in, monitored and given a drug to bring the rate down. Told I had a form of tachycardia and back in AF. BP still high & been told to see my cardiologist asap. I'm not sure how common this is, if it can revert back to NSR again etc. Back on Bisoprolol 5mg.
