<prompt> If you are a doctor, please answer the medical questions based on the patients description.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.  <response>: Hi welcome to Chat Doctor. I understand your query and concern. Bradycardia has to be dealt properly through adequate investigations.Its 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 6gday. Regular physical exercise in the form of brisk walk for 20 min a day for 5 days a week is pretty useful.
