Cardiology Questions Answered by Verified Cardiologists.
Hi, Dr. Stan here to help. How fast are you running on your treadmill? Is the 80bpm while running or before and how high does your heart rate get? You probably need to exercise at a lower rate while on the treadmill. Also, discuss your blood pressure with your doctor, you may need to reduce your Bisoprolol dosage to maintain a slightly higher blood pressure. I am here to answer any additional questions you may have. Please leave a positive rating of 3-5 stars. This is how I am credited for my response.
