Diagnostic Services and Procedures

Diagnostic Procedures are used to help assess and diagnose patients for cardiovascular disease. Diagnostic procedures are noninvasive and are performed in our clinics. 

Cardiovascular diagnostic procedures include:

Echocardiogram uses ultrasound waves to investigate and display the action of the heart as it beats. Procedures include:

  • Fetal to adult echodiagnostic procedures
  • Transesophageal echocardiography (TEE)
  • Stress echocardiography

Electrocardiogram (ECG) is a testing method commonly used to determine if the heart has been damaged. Also known as EKG, an electrocardiogram is a graphic record of the heart's electrical impulses.

Holter or Event Monitors are medical devices that record the heart's electrical activity. A holter monitor monitors your heart rhythm continuously for 24 to 48 hours. An event monitor records your heart's electrical activity when symptoms occur.

Echo Bubble Study is used to detect a hole in the heart. An echocardigram is used as a sterile salt solution is shaken until tiny bubbles form and then is injected into a vein. The bubbles will travel to the right side of your heart and appear on the echocardiogram. If there's no hole between the left atrium and right atrium, the bubbles will simply be filtered out in the lungs. If you have a hole in your heart (patent foramen ovale), some bubbles will appear on the left side of the heart.

Ankle - Brachial Index test compares your blood pressure measured at your ankle with your blood pressure measured at your arm. A low ankle-brachial index number can indicate narrowing or blockage of ther arteries in your legs, leading to circulatory problems, heart disease or stroke.

Ultrasound Vascular Study provides pictures of the body's veins and artieries. A vascular ultrasound is performed to help monitor the blood flow to organs and tissues throughout the body, it can identify and located blockages, detect blood clots and determine if a patient is a good candidate for certain procedures.

Pacemaker Check, a pacemaker needs to be checked regularly because over time a wire can get dislodged or brake; its battery may need to be replaced; your heart disease progresses; or other devices may have disrupted its electrical signaling.

Stress Tests
Stress tests fall into one of two categories: exercising on the treadmill or being given a medication which takes the place of exercise. A stress test may be ordered for various reasons, some of which may be:

  • To assist in the diagnosis of coronary artery disease
  • To help evaluate irregular heart rhythms
  • To help evaluate overall cardiovascular conditioning
  • To check the effectiveness of procedures done to improve coronary artery circulation in patients with coronary artery disease
  • To determine a safe level of exercise for those entering a cardiac rehabilitation program

Treadmill Stress Test
This test involves walking on a treadmill while a continuous 12-lead electrocardiogram, ECG, is monitored. The goal is to walk on the treadmill long enough to achieve a target heart rate based on your age. In most adults this can be achieved within four to nine minutes. Vital signs are monitored during the test.

Cardiolite Treadmill Stress Test (Also known as Nuclear Treadmill Stress Test)
This test involves walking on a treadmill while a continuous 12-lead EKG is monitored. An intravenous injection of the nuclear agent cardiolite also is done one minute before the treadmill is stopped. The goal is to walk on the treadmill long enough to achieve a target heart rate based on your age. In most adults this can be achieved within four to nine minutes. Vital signs are monitored during the test. After the treadmill exercise, you will be taken to the Nuclear Medicine department where two heart scans will be taken.

Treadmill Stress Echocardiogram
This test involves walking on a treadmill while a continuous 12-lead EKG is monitored. The goal is to walk on the treadmill long enough to achieve a target heart rate based on your age. In most adults this can be achieved within four to nine minutes. In addition, cardiac ultrasound images are taken by a sonographer before and immediately following the treadmill exercise. This will take an extra five to 10 minutes. Vital signs are monitored during the test.

Lexiscan Cardiolite Stress Test
This test is for people who are unable to walk on a treadmill, but do not have significant lung disease (such as emphysema or asthma). A continuous 12-lead EKG is monitored, and six-minute intravenous infusion of the medication adenosine is given. The medication does not increase heart rate, but helps blood vessels relax and open up. A nuclear tracer called cardiolite also is injected intravenously during the six-minute medication infusion. You then will be taken to the Nuclear Medicine department where two heart scans will be taken.

Dobutamine Cardiolite Stress Test
This test is for people who are unable to walk on a treadmill, and who also have lung disease (such as emphysema or asthma). A continuous 12-lead EKG is monitored, and an intravenous infusion of the medication dobutamine is given. The medication causes heart rate to increase, similar to when a person exercises. The medication is given for a period of time long enough to achieve a target heart rate based on age. In most adults this can be achieved within one to ten minutes. The nuclear tracer cardiolite then is injected into the intravenous line, and the dobutamine medication stopped. Vital signs are monitored during the test and until your heart rate returns to normal. You then will be taken to the Nuclear Medicine department where two heart scans will be taken.

Dobutamine Stress Echocardiogram
This test is for people who are unable to walk on a treatmill, and who also have lung disease (such as emphysema or asthma). A continuous 12-lead EKG is monitored, and an intravenous infusion of the medication dobutamine is given. A cardiac ultrasound is done before and during the medication infusion. The dobutamine medication causes heart rate to increase, similar to when a person exercises. The medication is given for a period of time long enough to achieve a target heart rate based on age. In most adults this can be achieved within one to ten minutes. Vital signs are monitored during the test and until your heart rate returns to normal.
