Diagnostic Tools

The latest technology

When it comes to diagnosing heart and vascular disease, speed matters. Our advanced diagnostic tools can help us identify and determine the best route of treatment for you quickly and efficiently.

Ankle-Brachial Index (ABI) and Segmental Pressure Testing

The blood pressure in your ankle is compared to the blood pressure in your arm.

Arterial Duplex

Harmless sound waves are used to create images of blood flow in your legs.

Cardiac Catheterization and Coronary Angiography

An angiogram is a special type of X-ray that lets your doctor view your coronary arteries to see if the blood vessels to your heart are narrowed or blocked. It requires your doctor to place a long, thin tube called a catheter inside an artery in your groin or arm and guide it into your heart.

Cardiac Stress Tests

Walking on a treadmill or riding a stationary bike to evaluate the blood flow to your heart, your exercise tolerance or the presence of a heart rhythm disturbance.

Computer Tomography (CT) Scan

A test that combines X-rays and computer scans to create a detailed picture that can show problems with soft tissues, such as the lining of your sinuses, organs, such as your kidneys or lungs, blood vessels and bones.

Echocardiograms (Echo)

An imaging test that uses sound waves (ultrasound) to create pictures of the heart.

Electrocardiogram (EKG or ECG)

This test records electrical signals from the heart onto a paper strip, measuring the heart’s rhythm, pumping quality and stress levels.

Electrophysiology Testing

Testing to find weak or damaged electrical pathways that make your heart beat too fast or slow. This helps your provider find the cause of a heart rate or rhythm problem and decide how to treat it.

Holter Monitors and Event Monitoring

A portable device used to record your heart’s electrical activity and help diagnose some kinds of abnormal heart rhythm and other health conditions.

Magnetic Resonance Imaging (MRI)

A test that lets your doctor see detailed pictures of the inside of your body by combining the use of strong magnets and radio waves to form an MRI image.

Nuclear Cardiology Testing

Testing that injects a very small amount of radioactive tracer into a vein while a sensitive camera takes still pictures and movies of the heart with rest, exercise or medication-induced stress testing.

Peripheral Angiography and Venography

An outpatient procedure that makes a “map” of the vessels (arteries) in your lower body, legs and arms, using X-ray and dye to show where blood flow may be blocked.

Tilt Table Testing

A simple test that helps pinpoint the cause of fainting by checking how changes in body position affect your blood pressure.

Transesophageal Echocardiogram (TEE)

A TEE is somewhat more involved than a surface echocardiogram as it requires a probe to be passed into your esophagus. Echo testing can help your doctor monitor changes in your heart over time.
