Noninvasive heart tests

Diagnosing a heart problem doesn't always involve surgery or an invasive procedure.

There are a number of noninvasive tests that can help your doctor learn more about how your heart is functioning.

These include EKGs, echocardiograms and exercise stress tests, which can be performed at Iredell Cardiology.

The health library includes a number of articles and other interactive ways to learn more about your heart.
