<s>[INST] Hi, my heart rate is 46 right now. It has been as low as 38. I have Bradycardia. I had a heart ablation Feb 12 for Atrial Fib. Now I am taking Sotalol. I see my heart surgeon next Friday. How low is too low? I am 70 years old. I have been considered athletic. Before the ablation, my normal low limit on my sport watch was set to 45. [/INST] Hi welcome to Chat Doctor. I understand your query and concern. Bradycardia has to be dealt properly through adequate investigations.It's can be treated through procedures like implantable cardiac pacemakers. Chat Doctor. I advise you to have a baseline 2 dimensional echocardiography, ECG and lipid profile to assess the basic cardiac reserve of your heart. Restrict the intake of salt to less than 6g/day. Regular physical exercise in the form of brisk walk for 20 min a day for 5 days a week is pretty useful. </s>
