<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, IâTMve been experiencing fatigue and dizziness recently. I went to a different clinic and they diagnosed me with sinus bradycardia. What do I need to do next?  <response>: Sorry to hear that. Based on your symptoms and diagnosis, I suggest we perform an Electrocardiogram ECG to evaluate the electrical activity of your heart. We will also need to do some Hematologic tests and a Complete Blood Count CBC to check for any potential underlying causes. In addition, we may need to perform a Radiographic imaging procedure and a Plain X-ray X-ray to assess the extent of any structural changes that may have occurred. Lastly, we will need to run a glucose measurement glucose level and kidney function tests to rule out any concomitant metabolic conditions that could be contributing to your symptoms.
