Non-Invasive Cardiology (Diagnostic Testing)
Non-Invasive Cardiology at Elliot Hospital offers an extensive variety of cardiac testing. Our skilled and dedicated staff works closely with patients to alleviate fears by providing thorough explanations and supporting patients through their entire procedure.
A common test to evaluate how the heart performs during exercise. This test is often done to diagnose the presence of coronary artery disease, or to administer adequate medical therapy. You may also hear exercise tolerance test called exercise stress test, stress tests, exercise EKG's or treadmill tests.
MIBI STRESS TEST
A MIBI Stress Test is a study that combines exercise tolerance testing and nuclear imaging to evaluate blood flow to your heart muscle. MIBI is a low level isotope used to highlight the heart muscle and evaluate its blood supply. This test is used to diagnose the presence of coronary artery disease. It is usually performed when patients have angina, unexplained chest pain, shortness of breath, or known coronary artery disease.
ADENOSINE MIBI STRESS TEST
An Adenosine Mibi Stress Test is a study that combines exercise tolerance testing and nuclear imaging of the heart to evaluate coronary blood flow. Adenosine is a medication used to dilate coronary arteries and simulate the effect of exercise on the heart. This medication is ordered if the patient cannot exercise to a high enough level to obtain an adequate stress result. The test can be done with or without walking on a treadmill.
EXERCISE STRESS ECHOCARDIOGRAM
A test that combines an ultrasound study of the heart ( echocardiogram ) and an exercise tolerance test . This test helps to identify areas of decreased blood flow to the heart muscle or blockages in the coronary arteries.
DOBUTAMINE STRESS ECHOCARDIOGRAM
A Dobutamine Stress Echocardiogram is a test that combines an ultrasound study of your heart ( echocardiogram ) with a medically induced stress test. Dobutamine is a medication to make the heart beat faster and more forcefully. This simulates the effect of exercise in those who are unable to walk on a treadmill. This test helps to identify areas of abnormal blood flow to the heart muscle, caused by blockages in the coronary arteries.
An Echocardiogram is a noninvasive procedure that uses sound waves (ultrasound) to evaluate how well the heart is working. This test will help the doctor to evaluate the size, pumping strength and function of the heart muscle and valves.
A pediatric echocardiogram is an ultrasound study of the heart done specifically on children. Elliot hospital's echocardiography technicians have specialized training for the pediatric population.
A transesophageal echocardiogram (TEE) is a test that doctors use to obtain images of the heart from inside the esophagus (swallowing tube). The esophagus lies immediately behind the heart and with this technology; very clear images of the heart can be obtained. This test is used by doctors to visualize structures of the heart not seen by a standard echocardiogram (from the outside chest wall) as well as clarify structures that may be otherwise poorly seen.
An Electrocardiogram (ECG or EKG) is a noninvasive test that records the electrical activity of the heart. EKG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker).
Holter monitoring provides a continuous recording of heart rhythm during normal activity. The monitor is usually worn for 24 hours to obtain a recording of a complete day. This test will help the doctor evaluate the type and amount of irregular heartbeats during regular activities, exercise and sleep.
MICROVOLT T WAVE ALTERNANS
The Microvolt T-Wave Alternans test is a noninvasive diagnostic test designed to help identify patients at risk of life threatening heart rhythm disturbances that can lead to sudden cardiac death. The Microvolt T-Wave Alternans Test can identify subtle electrical disturbance in your heart.
SIGNAL AVERAGE ELECTROCARDIOGRAM
The Signal Average Electrocardiogram (SAECG) is a non-invasive test that records the heart's electrical activity. It is like the electrocardiogram but uses specialized computer processing to magnify the heart muscle's signal and search for abnormal electrical activity. This can help identify individuals at risk for developing life-threatening arrhythmias.
UPRIGHT TILT TEST
An Upright Tilt Table Test (Tilt Test) is used to assess symptoms such as dizziness, lightheadedness and/or syncope (fainting, passing or "falling" out). It is performed to try to reproduce the symptoms while being monitored. Lightheadedness or syncope can result from a rapid fall in blood pressure, which can occur when moving from a supine (flat) or sitting position to a standing position. It sometimes involves reflex receptors in the heart, which may prevent the heart from beating quickly or forcefully enough to provide sufficient blood flow to the brain. This can result in the symptoms described above. The tilt table test is a procedure that involves monitoring your heart rate and blood pressure in both the supine and upright positions in an effort to uncover this abnormal reflex.
A Cardioversion (electrical Cardioversion) converts certain types of abnormal heart rhythms (arrhythmias) to normal ones. It accomplishes this with a well-controlled and perfectly timed electrical shock to the chest wall.
