Cardiology Tests

Diagnosing Your Symptoms

Carondelet doctors and specialists offer a full range of diagnostic services using state-of-the-art techniques and technology. These tests can help in the diagnosis or detection of disease. Some of the comprehensive, minimally invasive tests we offer at our advanced facilities include:


Also known as an echocardiogram or echo test, echocardiography uses ultrasound to create images of your heart that show its size, structure and motion. It is more detailed than a standard X-ray. It provides valuable information that can be used to detect abnormal heart rhythms (arrhythmias), congenital heart disease, heart failure and heart valve disease. Three-dimensional echocardiography is the most technologically advanced form of this testing method.

Transesophageal Echocardiograms

This test uses sound waves to create moving images of the heart and blood vessels. To do perform this test, a doctor will guide a flexible tube called a probe down your throat and into your esophagus, which is directly behind the heart. This allows doctors to get a detailed picture of the heart.

Computed Tomography (CT) Angiography

CT angiography uses a CT scanner to create detailed images of blood vessels and tissues. This is done by injecting dye into a catheter that’s placed into a vein in the arm. The CT scan will watch how this dye flows through the blood vessels to various parts of the body.

Exercise Stress Test

An exercise stress test measures the effect of exercise on your heart. After a technician places flat, sticky patches called electrodes on your chest, you’ll be asked to walk on a treadmill while your heart’s activity is measured.

Stress Echocardiography

Stress echocardiography uses ultrasound imaging to determine how well your heart muscle is pumping blood to your body. It’s mainly used to detect a decrease in blood flow to the heart, indicative of coronary artery disease.

Nuclear Stress Testing

A nuclear stress test shows how well blood flows into your heart muscle, both while at rest and while exercising. For the resting portion, you will have an IV started and a special camera will take pictures of your heart. For the exercise portion, you’ll walk on a treadmill while your blood pressure and heart rhythm are monitored. This test can also be performed using a medication to mimic physical activity if you’re unable to exercise.

Dobutamine Stress Testing

Dobutamine stress testing is used when exercise stress testing is not an option, due to a medical condition. A doctor may use an IV medication called dobutamine to mimic the effects of exercise on the heart, causing it to beat faster. Then, ultrasonic sound waves are used to create images of the heart walls and valves.

Elective Cardioversion

A cardioversion is a procedure that returns an irregularly beating heart (arrhythmia) back to a normal pattern using a carefully controlled electrical impulse that is delivered to the heart.

Diagnostic Right and Left Heart Catheterization

Cardiac catheterization involves passing a thin, flexible tube called a catheter into the right or left side of the heart, usually from the groin or the arm. From there, the doctor can assess many aspects of heart health, including the oxygen and blood flow in various parts of the heart.
