Whether the cardiologist sees you in the office or in the hospital, he or she will review your medical history and perform a physical examination which may include checking your blood pressure, weight, heart, lungs, and blood vessels. Some problems may be diagnosed by your symptoms and the doctor’s findings when you are examined. You may need additional tests such as an ECG, x-ray, or blood test. Other problems will require more specialized testing. Your cardiologist may recommend lifestyle changes or medicine. Each patient’s case is unique.
