Nuclear Stress Test

A nuclear stress test is another method used to evaluate blood flow in the heart. This test is a more sensitive and diagnostic method of screening and evaluating for Coronary Artery Disease that may be obstructing blood flow. A nuclear stress test uses a radioactive tracer to produce pictures that show the blood flow in the heart at rest and during exercise/stress. This test involves a small IV being placed and the radioactive tracer is injected before and during exercise/stress. X-ray pictures are also obtained at rest and after exercise/stress. The exercise part of the test is performed on a treadmill or if the patient cannot walk safely on a treadmill, a “chemical stressor” will be used. This study takes 3 ½ to 4 hours and specific instructions on how to prepare will be provided by Camp Lowell Cardiology.

Carotid Ultrasound

Carotid ultrasound uses sound waves to produce pictures of the carotid arteries in the neck.  This test is obtained to evaluate the structure of the carotid arteries and observe/measure blood flow.  Carotid ultrasound is used to screen for blockage or narrowing of those arteries that may increase the risk of stroke.  This is a simple procedure that involves laying still while ultrasound gel is applied, and a hand-held wand is moved over the sides of the neck.

Abdominal Aorta Ultrasound

An abdominal aorta ultrasound uses sound waves to image the aorta which is the main blood vessel leading away from the heart. This test is often obtained to screen or monitor an Abdominal Aortic Aneurysm (AAA) which is a condition in which the lining of this vessel is enlarged. This is a simple, brief procedure in which ultrasound gel is applied and hand-held wand is moved over the upper abdomen.

Device Monitoring

There are multiple devices that are placed in the body to monitor and treat conditions that effect heart rate/function. Pacemakers are placed for a heart rate that is too slow and defibrillators (ICD) are inserted for heart rhythms that are too fast. Cardiac Resynchronization Therapy (CRT) is a pacemaker to treat congestive heart failure and Loop Recorders are implanted to record heart rhythm disorders. All of these devices require regular evaluation/monitoring in the office and some can also be monitored remotely via a device in the home.


An electrocardiogram is also known as an ECG or EKG and is a “snapshot” of the electrical activity traveling through the heart. The ECG is routinely used as a screening tool and is a simple test to obtain.  Several electrodes (stickers) are applied to the chest while laying down on an exam table and the tracings are printed out over a few seconds.  It is best to have clean skin without lotion and shaving may be required for placement of the electrodes.

Continuous Remote monitoring

Monitoring of heart rate and rhythm is often helpful in evaluating symptoms such as palpitations or dizziness or fainting. It is used to look for issues with heart rate or conduction. A monitor can be worn for 24 hours up to 4 weeks. There are options on what type of monitoring device is used but most often it involves stickers placed on chest with small wires. There is also a lightweight necklace worn with a small box attached. All normal activities can be performed while wearing the monitor and it is briefly removed for showering/bathing.


An echocardiogram is also called an “echo” and is an ultrasound of the heart. Echocardiography uses ultrasound waves that make images of the heart chambers, valves and surrounding structures. This test is used to evaluate the size and function of the heart and also determine how the heart valves are working. Many treatment decisions made by your cardiologist and other health care providers are based on the results of an echo. There is little to no special preparation for this procedure that takes 30-45 minutes while laying still on an exam table. Ultrasound gel is applied to the chest and a hand-held wand is placed on the chest and moved around to capture images.

Exercise Stress Test

A standard exercise stress test is also known as a treadmill test. It is a procedure that is used for screening purposes as well as evaluation of cardiac-related symptoms. A stress test observes how the heart responds to exercise or stress. Most often, this test is used to screen for Coronary Artery Disease (CAD) that may be reducing blood flow to the heart. After several electrodes are placed on the chest, the patient walks slowly on the treadmill. There is a gradual increase in speed and tilt in the treadmill to produce the effect of walking up a small hill. The treadmill is stopped once the patient has reached their personal maximum amount of exercise. The heart is monitored by an ECG and there is constant supervision during this test. Please wear appropriate walking shoes and a loose-fitting shirt that buttons in the front is also recommended.
