There are many tests that can be done to check heart function. At a bare minimum you should have your blood pressure, cholesterol levels and heart rate checked. If you have symptoms of heart disease such as chest pain, pain on exertion or palpitations or if you have existing risk factors (in addition to family history other risk factors include smoking, high blood pressure, cholesterol, and diabetes) then your doctor may order any one of a number of tests such as an exercise stress test, electrocardiogram, echocardiogram, holter monitor and CT scan to name a few.
