Diagnostics and Testing:
Our cardiologists and other providers are skilled in performing the most advanced diagnostic tests available to detect heart conditions and determine patients' risk for heart disease. Our clinic is equipped with the very latest technology bringing state-of-the-art diagnostics to The Dalles.
Medical history and physical examination: A comprehensive medical history and physical exam is the first step in treating patients with, or at risk of, heart disease. We will assess your cardiovascular health while learning about you, your lifestyle and your quality-of-life goals.
Electrocardiography (EKG or ECG): Electrocardiography is a commonly used, non-invasive procedure for recording electrical changes in the heart. It's a starting point for detecting many cardiac problems. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses, which occur during each beat of the heart. The results are printed on paper or displayed on a monitor.
Exercise Stress Test: Also known as a treadmill test, an exercise electrocardiogram is a test that checks for changes in your heart while you exercise.
Electrophysiology: Electrophysiology studies, or EPS, use cardiac catheterization techniques to study patients with irregular heartbeats (called arrhythmias). EPS shows how the heart reacts to controlled electrical signals. Any dysfunction in the heart's electrical conduction system can make the heart beat too fast, too slowly, or at an uneven rate, thus causing an arrhythmia.
Event Monitoring: Also called ambulatory monitoring, this "real-time" test looks for evidence of heart problems that come and go and that are not apparent when a standard ECG is performed. Ambulatory monitoring is particularly useful in diagnosing heart arrhythmias and cardiac ischemia.
Echocardiogram: An echocardiogram is a diagnostic examination of a person's heart. Doctors use high-frequency sound waves (ultrasound) to look at the size, shape and motion of the heart. In addition to the standard test, there are specialized echocardiograms:
- Stress echocardiogram: This test stresses the heart through exercise or an injection to measure how the heart responds.
- Myocardial Contrast Echocardiography: This new technology allows physicians to use "microbubbles" for a more accurate diagnosis in certain conditions.
Cardiac Catheterization: Performed at OHSU, cardiac catheterization involves passing a thin flexible tube, called a catheter, through an artery or a vein to the heart, and into a coronary artery. This procedure produces X-ray images (called angiograms) of the coronary arteries and the left ventricle, the heart's main pumping chamber. They also can be used to measure pressures in the pulmonary artery and to monitor heart function.
