Screenings and tests
Identifying a person's risk of heart disease with early detection

Echocardiogram (ECHO)
Ultrasound is one of the most widely used diagnostic procedures available. It provides a safe, non-invasive and virtually painless means of observing soft tissue anatomy on an outpatient basis.
An echocardiogram is a safe, non-invasive ultrasound imaging procedure used to assess cardiac function. Echocardiography allows doctors to visualize the anatomy, structure, and function of the heart. The echocardiogram can show:
An echocardiogram is a safe, non-invasive ultrasound imaging procedure used to assess cardiac function. Echocardiography allows doctors to visualize the anatomy, structure, and function of the heart. The echocardiogram can show:
- all four chambers of the heart
- the heart valves
- the blood vessels entering leaving the heart
- the sack around the heart.

Electrocardiogram (EKG)
The electrocardiogram is a device capable of recording the electrical activity of the heart from electrodes placed on the skin in specific locations.
Physicians use this information to discover such things as:
Physicians use this information to discover such things as:
- heart rate.
- arrhythmias.
- myocardial infarctions.
- atrial enlargements.

Heart monitoring
Event Monitor
An event monitor is issued for a 30 day period. Two patches are applied to the chest and connected by wires to a small transmitter. Patches are changed daily by the patient, allowing for bathing. Over a 30 day period, the patient takes a recording when an event or episode occurs. The recording is then transferred via a landline phone to the monitor lab. Physicians utilize this information for heart rhythm abnormalities. This requires a 30 minute appointment.

Stress tests
A stress test, sometimes called a treadmill test or nuclear stress test, helps determine how well the heart handles work. As the patient walks on a treadmill or is given medication to stress the heart, an EKG machine monitors the heart rate, breathing, blood pressure, the electrical activity of the heart, and exercise tolerance. With a nuclear stress test, there are two parts to the test: a resting study and a stress study
A Nuclear Stress Test is used by doctors to diagnose and monitor heart disease.
During a Nuclear Stress Test, a safe amount of a radioactive drug is injected into your vein which allows the cardiologist to see how well blood is flowing to and through your heart.
The test, usually conducted over two days, consists of taking images of your heart in two phases: a stress phase and a resting phase.
There may be restrictions as you prepare for this test. Please ask your health care provider.
