Has anyone had a similar experience? Two weeks after my ablation my resting heart rate shot up from 75-80 to 120-130 bpm. After 24 hours it had not gone down, so I saw my GP who ran an ECG and confirmed that my heart rate was high. He suggested that I increase my Sotalol medication from 80mg a day to 120 mg. So far (48 hours later) this has had no effect. I know that there are ups and downs after an ablation as the heart heals, but is this normal? And how long can I expect to have such a high heart rate? Any thoughts from fellow sufferers would be very welcome.
