Heart rate always above 90 male 5'2 133 lb doc gave me inderal, (propranolol) should I insist on cardiologist referal? I can barely walk without getting very tired

Heart rate. There is not enough information here to know if you should see a cardiologist. You should ask your doc to explain what he/she believes is going on and whether cardiology consult is appropriate. Are you out of shape? Does the doctor believe a cardiac abnormality is present?
