What Is a Cardiomegaly?
4. Diagnosis
Imaging tests are commonly used to diagnose cardiomegaly because they are able to measure the size of the heart as well as its electrical activity and blood movement through the valves and chambers. If you suspect that you have an enlarged heart, your doctor may recommend one or more of the following: CT scan, chest X-ray, electrocardiogram, or echocardiogram.
If your doctor determines that you do have cardiomegaly, he or she will likely order further testing to help determine the underlying cause of your condition. Such testing may include blood tests, a full physical exam, a stress test, or a cardiac catheterization.
