[|AI|]  Hi welcome to Chat Doctor. I understand your query and concern. Your symptoms are suggestive of with Chat Doctor. Atrial fibrillation is known to cause Rapid heart rate and fluctuations in blood pressure. 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 daily is useful. Avoid taking caffeine.
