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.
By itself the EKG will not pinpoint a blockage, an IVUS procedure will do that. The EKG will show if the heart muscle has weakened which is caused by lack of blood from a blocked artery. The IVUS procedure can then help pinpoint the vessel and monitor treatment such as angio, stenting or worse case by-pass.
