An accurate diagnosis of heart and vascular disease starts here.

Our outpatient Cardiac Diagnostic Centers adhere to standards set forth by the Inter­societal Commission for the Accreditation of Echocardiography Laboratories, Nuclear Medicine Laboratories and Vascular Laboratories. Being accredited demonstrates a commitment to quality care. The accreditation process allows laboratories to assess every aspect of daily operations and its impact on the quality of healthcare provided to patients in comparison with other laboratories nationwide. It allows the laboratory to use proven quality assurance measures and provides a confidential peer-review of practices within the laboratory.

Diagnostic procedures we perform include:

Abdominal aortic aneurysm ultrasound

Doppler ultrasound uses sound waves to create images of the aortic blood vessel from the chest to the abdomen.    

Ambulatory cardiac monitoring

Holter, loop and event monitoring

Portable devices worn for one or several days record the heart’s activity while patients are going about their daily lives, to help physicians better understand and diagnose cardiac anomalies.

24-hour blood pressure monitoring

Small digital blood pressure monitors connected to a cuff on the upper arm that measure blood pressure over the period of 24 hours to determine if there are consistent problems associated with either activity or rest.

Ankle brachial index (ABI)

A test that measures blood pressure at both the ankle and the arm while you are sitting or resting.

Aortic ultrasound

Doppler ultrasound uses sound waves to create images of the aortic blood vessel from the chest to the abdomen.

Bubble study

Sterile saline is injected into the veins after it is mixed in two syringes, creating tiny bubbles in the saline. The bubbles are followed in the heart to determine if they follow the normal pathway of blood flow.

Cardiac stress testing

A stress test may be performed with or without what is called a “nuclear” component. The traditional stress test is performed on a treadmill while an electrocardiogram is produced recording the heart’s activity. A “nuclear” stress test begins in the same manner but also involves an injection into your arm of a small amount of a radioactive chemical that travels throughout your heart to produce clear images of heart tissue taken with a special camera. 

Carotid ultrasound

Doppler ultrasound uses sound waves to create images of the carotid blood vessel on both sides of the neck.

Coronary angiography

A special dye is injected into the artery after which X-rays are taken to show the circulation of the heart. This test can determine if there are blockages or other structural defects present.

Electrocardiogram (EKG)

Sensors are placed in the chest area and at other pulse points to record the heart’s activity.

Electrophysiology studies

A minimally invasive procedure that looks at the electrical signals of the heart to determine if there are abnormal beats or rhythms.

Implantable loop recorder

A device is surgically inserted under the skin (in the chest area) to record abnormal rhythms for an extended period of time.

Iliac artery ultrasound

Sound waves are used to examine the abdominal aortic and iliac arteries in the leg and determine if the blood vessels are narrowing or if there are blockages.

Peripheral angiography

A diagnostic study using X-rays to learn if there are blocked arteries in either the legs or lower portion of the body.

Pulse volume recording (PVR)

A noninvasive test to measure blood flow in the arms and legs.

Renal artery ultrasound

Sound waves are used to create images of the arteries that supply blood to the kidneys.

Stress echocardiograms

An echocardiogram is used to measure your heart’s activity both before and after exercise.

Upper and lower extremity ultrasound

Sound waves are used to create images of the arteries in the legs and arms.

Vascular studies (for PVD)

Noninvasive testing of the blood flow in the arteries and veins that involves the use of a mechanism called a transducer which, when placed on the skin, uses sound waves to identify problems.

Vessel mapping

Physicians create an actual “road map” of the pattern of blood vessels and arteries. The “road map” can be used to assess blood flow or in preparation for procedures such as hemodialysis.

2D echocardiograms

Pictures of the beating heart are created showing cross sections — also called “slices” — displaying all chambers, valves and blood vessels.
