Finding the cause of heart trouble

To help ensure an accurate and thorough diagnosis, the cardiac diagnostic center at Methodist Charlton offers a wide variety of diagnostic tests and procedures for heart problems. Our new flat-plate digital catheterization lab features some of the latest technologies in imaging, electrophysiology and catheterization.

Our complete suite of heart disease diagnostic services at Methodist Charlton includes:

Cardiac catheterization—invasive test that allows your physician to identify blockages in the arteries of the heart. A special X-ray dye is injected into a large artery in the leg, and then several X-ray pictures of the heart are taken while you rest comfortably.

Computed tomography (CT)--these scans help identify the buildup of calcium in the heart arteries by creating a three-dimensional image of the heart. A special dye is injected into a vein, and then a scanner rotates around the body, capturing images of the heart from several different angles. A computer then combines the images to create a picture of the whole heart.

Echocardiograms—use ultrasound waves to create images of the heart, which can provide information about the heart’s structure and function and may diagnose a multitude of heart problems. These tests are available for both adults and children.

Electrocardiograph (ECG or EKG)—quick, noninvasive test that measures the heart’s electrical activity using electrodes placed on the chest.

Holter monitoring—involves a small, noninvasive device worn to provide a continuous, 24-hour record of the heart’s electrical activity during normal daily activities so that rhythm disturbances may be identified by your Methodist Dallas physician.

Nuclear medicine scan stress tests (also called myocardial perfusion scans)—use a radioactive contrast agent that is injected into a vein, along with a special X-ray camera placed over the chest, to identify healthy and unhealthy heart tissue. The scan is done while you are resting and again after you walks or jog on a treadmill or use medicine to speed up the heart.

Stress testing—noninvasive procedure that assesses heart activity while the heart is being stressed during an exercise period. It may detect heart problems that aren’t apparent when the heart is at rest.

Transesophageal echocardiograms—use a special probe that is inserted into the esophagus in the throat until it’s very near the heart. Just like a regular echocardiogram, it emits sound waves that produce an image of the heart; but, because the probe is closer to the heart, the images it produces are clearer than those seen with a normal echocardiogram.
