Cardiac Testing

Stress Testing/Stress Echoes
Stress testing provides information about how your heart works during physical stress.  During stress testing, you exercise (walk or run on a treadmill) to make your heart work hard and beat fast while being monitored by a cardiovascular technologist. 

  1. Treadmill – come prepared to exercise in comfortable clothing with tennis shoes

  2. Pharmacological -  if you are physically unable to use the treadmill, you will be given a medicine to make your heart work harder.

 A stress echo is performed in conjunction with the stress test.  An ultrasound image is obtained of the heart before and after exercise to offer more diagnostic information

Cardiolite – done in conjunction with nuclear imaging. Similar to a regular stress test, this involves exercise (walk or run on a treadmill) while being monitored by a cardiovascular technologist, but in addition computer images are taken by a nuclear technologist before and after exercising. While this procedure takes longer than a traditional stress test, the results are more detailed, aiding in diagnosis.

Cardiac Testing instructions are available from your physician’s office.

Vascular Testing

In most cases, with early detection, vascular disease can be treated effectively. There are several simple screening tests that detect these problems, all of which are non-invasive and painless.

Carotid Doppler- This test uses sound frequency to produce images of the carotid arteries in the neck on a viewing screen. The blood flow through these arteries is evaluated with Doppler and Color Doppler.

Venous Duplex of Extremities- The most common reason for a venous ultrasound exam is to search for blood clots, especially in the veins of the leg.

Arterial Duplex of Extremities- Two-dimensional ultrasound imaging of the major arteries in the extremities. Allows the physician to assess for any abnormalities in the blood flow.

Arterial Physiological Testing

  1. ABI’s – Arterial/Brachial Index This test is done by measuring blood pressure at the ankle and in the arm while a person is at rest. Measurements are usually repeated at both sites after 5 minutes of walking on a treadmill.  This test is done to screen for peripheral arterial disease of the legs

  2. Doppler - A Doppler ultrasound test uses reflected sound waves to see how blood flows through a blood vessel. It helps doctors evaluate blood flow through major arteries and veins, such as those of the arms, legs, and neck.

  3. Segmental Pressures/VPR’s - A test that measures the blood pressures in the legs to make sure there is normal blood flow. The test is usually done when there is intermittent claudication (leg pain on exercise).

Venous Ablation procedures

for varicose veins and chronic venous insuffiency This procedure is performed under ultrasound guidance with Dr. Lame performing the ablation.

Cardiac Echo/Doppler

An echocardiogram is a test in which ultrasound is used to examine the heart.  Doppler is a special part of the ultrasound examination that assesses blood flow giving the physician valuable information of the size of the heart chambers and the pumping function of the heart.

  1. Adult

  2. Pediatric

Holter Monitoring/Event Monitoring


A Holter monitor is a continuous tape recording of a patient's EKG for 24 hours – 48 hours.  Since the recording is on a continuous basis, Holter monitoring is much more likely to detect an abnormal heart rhythm when compared to the EKG which lasts less than a minute. Event monitoring involves wearing a very small, portable, EKG recorder over a period of time that can vary from weeks to a month. When a patient is having an event, he or she just pushes a button to record what is happening with the heart. The recorded data can be sent over the phone to your doctors for analysis

  1. 24 hr.

  2. 48 hr.

  3. 30 days
