You should have your blood pressure checked at least once a year.

If you are diagnosed with high blood pressure or hypertension, your doctor may recommend that you take the following tests to detect damage to the heart or blood vessels.

Electrocardiogram (ECG). A noninvasive test that helps to assess the extent of damage, if any, of heart muscle.

Echocardiogram. An ultrasound examination of the heart that helps to assess the blood supply to heart muscles indirectly. It also measures the strength of the heart muscle.
