Advanced Cardiopulmonary Diagnostic Services

UMCP Logo Pastoral Care UMCP Logo Pastoral Care

Princeton Medical Center offers state-of-the-art diagnostic imaging to help detect and evaluate cardiovascular, pulmonary and respiratory conditions. These services are essential to assessing, treating and promoting heart and pulmonary health and function.

All tests performed at Princeton Medical Center are conducted by highly trained cardiac, echocardiography and pulmonary technicians working under the direction of the medical director who is board certified in cardiology, pulmonology and echocardiography. We are committed to promptly reporting your test results to your personal physician or cardiologist to promote fast and effective treatment.

cardiac testing

The Center offers a comprehensive range of advanced diagnostic testing for cardiac and pulmonary issues, including:

Diagnostic Cardiology


An echocardiogram, an ultrasound of your heart, is a painless, noninvasive procedure used to diagnose structural defects, coronary artery disease (CAD), cardiomyopathies, and the cause of cardiac murmurs. The Echocardiogram Laboratory at Princeton Medical Center is a sophisticated facility that has achieved national accreditation by the Intersocietal Commission for Accreditation of Echocardiography Laboratories (ICAEL). Our fully digital imaging system for echocardiography captures detailed images of valve function, blood flow and cardiac anatomy. Results are stored in a digital video that can be reviewed and interpreted by the cardiologist when evaluating and managing ongoing heart defects and valvular diseases.

Test Time – 1 hour

Stress Echo

A stress echo involves having an echocardiogram performed while the patient is at rest and again following physical activity to determine how the heart functions under stress. This test is used to diagnose coronary artery disease. Treadmill or pharmacological studies are performed.

Test Time – 1 1/2 hours

Back to Top

Nuclear Stress Test

Nuclear stress testing assesses blood flow to the heart to detect the presence or significance of coronary artery disease. The patient is injected with a radioactive isotope at rest and again at peak exercise. Each injection is followed by radiographic imaging of the heart to detect the presence of the injected compound. The stress portion of the test may be achieved on a treadmill or induced pharmacologically with either Persantine, Adenosine or Dobutamine.

Test Time – 3 to 4 hours

Cardiac Stress Test

A cardiac stress test utilizes continuous EKG (electrocardiogram) to determine the presence or absence of heart disease and/or evaluate the effectiveness of current therapy for a cardiac condition.

Test Time – 1 hour

Electrocardiogram (EKG)

PMC’s electrocardiogram technology records electrical activity of the heart, quickly providing essential information about heart rhythm, condition and function while also identifying ischemic changes and irregular beats. The Princeton Medical Center’s EKG Management System is fully networked within the hospital and with other Princeton Health facilities for fast sharing, review and interpretation of EKGs.

Test Time – 15 to 20 minutes

Holter Monitoring

The holter monitor is a personal device worn by the patient that records electrical signals of the heart during a 24-hour period. The device aids in the detection of abnormalities in heart rhythm or the cardiac conduction system. Symptoms such as palpitations, fainting spells, dizziness and chest discomfort can be recorded and used to correlate a patient’s symptoms with cardiac rhythm.

Test Time – Device is worn for 24 hours

Transtelephonic/Event Monitor

The transtelephonic/event monitor records intervals of a patient’s cardiac electrical activity whenever the patient experiences transient cardiac symptoms during his or her daily activities. The device helps determine the presence or absence of clinically significant cardiac arrhythmias. The recording is sent via telephone to a receiving station where the data is interpreted by a physician.

Test Time – Device is used for two to three weeks

Loop Monitoring

For patients with intermittent symptoms or cardiac events, loop monitoring provides an effective, patient-activated approach to recording valuable EKG data prior to and after the patient experiences a symptom.

Test Time – Device is used for two to three weeks

Pulmonary Procedures

Pulmonary Function Test (PFT)

A pulmonary function test determines the origin and extent of respiratory disease and response to therapy. PFTs are also effective for preoperative evaluation of lung function.

Test Time – 1 hour

Pulmonary Exercise Test

The pulmonary exercise test evaluates pulmonary, cardiac and muscular parameters revealing the functional status of the cardiopulmonary system. The test provides a helpful assessment of the effects of medication, surgery, diet and physical conditioning and is recommended before starting a rehabilitation program.

Test Time – 2 hours

Bronchial Provocation Test

The bronchial provocation test, also known as methacholine challenge, assists in the diagnosis of asthma (bronchial airway hyperactivity) by measuring expiratory flow rates.

Test Time – 1 to 2 hours

Arterial Blood Gas Test (ABG)

An ABG is used to determine the levels of oxygen, carbon dioxide and blood PH in a patient’s blood.

Test Time – 30 minutes


In patients afflicted by smoke inhalation and/or carbon monoxide, the co-ox blood sampling helps determine the level of carbon monoxide present in the blood.

Test Time – 30 minutes

Pulse Oximetry

Pulse oximetry is a non-invasive method used to detect a patient’s oxygen level.

Test Time – 30 minutes
