The system calculates how much blood is flowing through diseased coronary arteries that have narrowed due to a buildup of plaque. The patient does not need an invasive angiogram that involves threading a catheter to the heart.

What does a normal ECG indicate?

An ECG (electrocardiogram) records the electrical activity of your heart at rest. It provides information about your heart rate and rhythm, and shows if there is enlargement of the heart due to high blood pressure (hypertension) or evidence of a previous heart attack (myocardial infarction).
