And EKG won't directly detect a blockage but it can detect changes in the why the heart is functioning because of blockages and damage to the heart muscle which has been caused by blockages. An EKG measures the movement of electrical charges through the heart. The measurement appears as a wave with ups and downs.
Another pattern (ST depression) suggests ischemia - or a lack of blood supply to part of the heart again is suggestive a partial blockage. A resting ECG may be normal despite a blockage. Contrary to popular belief a NORMAL ECG does NOT exclude blockages. The use of excercise (treadmill) or certain medications to increase heart rate (work load on the heart) increase the likelyhood that changes will be found suggesting blockage.
