Atrial fibrillation is known to cause fluctuations in blood pressure. You are currently placed on right kind of 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.
