Diagnostic Tests

Diagnostic Tests

Physicians at the University of Maryland Heart Center use a wide variety of diagnostic tests to determine if you have heart disease and to see how your disease is progressing.

Here's a list of some of the diagnostic tests and evaluations available at the Heart Center:

  • Angiography - An X-ray that uses dye injected into the coronary arteries so that blood circulation canPhoto of a graph be studied.
  • Cardiac Catheterization - A diagnostic procedure in which a tiny, hollow tube (catheter) is inserted into an artery in the leg or arm in order to determine the location and severity of blockages.
  • Coronary Calcium Scoring/Heart Scan - A non-invasive test performed on a computed tomography (CT) machine that can help evaluate your risk of heart disease in less than an hour.
  • Echocardiography - This test uses sound waves to produce a study of the motion of the heart's chambers and valves.
  • Electrocardiogram (ECG or EKG) - A routine test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias or dysrhythmias), and enlargement or damage to the heart muscle. 
  • Electrophysiology Studies - A test in which insulated electric catheters are placed inside the heart to study and treat disorders involving the heart's electrical system.
  • Exercise Stress Tests (Treadmill Tests) - A test that is given while the patients walk on a treadmill to see if exercise brings on changes to the ECG.
  • Holter Monitor - A small, portable, battery-powered ECG machine worn by a patient to record ECGs on tape over a period of 24-48 hours. At the end of the time period, the monitor is returned to the doctor's office so the tape can be read and evaluated.
  • Intravascular Coronary Ultrasound (IVUS) - A combination of echocardiography and a cardiac catheterization, IVUS uses sound waves to produce an image of the coronary arteries and to see their condition. The sound waves are sent through a catheter, which is threaded through an artery and into your heart. This test lets doctors look inside your blood vessels. IVUS is rarely done alone or as a strictly diagnostic procedure. Instead, it is usually done at the same time that a transcatheter intervention like angioplasty is being performed.
  • Rubidium PET/CT Scanning - This noninvasive imaging technology helps doctors make a precise diagnosis of heart disease, as it allows doctors to obtain information about the heart's anatomy and function in the same setting.
  • Tilt Table Test - A test performed while the patient is connected to ECG and blood pressure monitors and strapped to a table that tilts. This test is to determine if the patient is prone to sudden drops in blood pressure or slow pulse rates.
  • Transradial Cardiac Catheterization - Offers a less invasive, lower-risk option because the procedure is performed through the wrist rather than the groin.
  • Transesophageal Echocardiography - Like standard echocardiography, transesophageal echocardiography uses sound waves to produce an image of the heart. But unlike standard echocardiography, the sound waves are sent through a tube-like device that is put in the mouth and passed down the throat into the esophagus.
