Instrumentation for coronary-artery disease

DETECTION of coronary-artery disease has long been a serious medical problem. A well-known manifestation of this disease is a “heart attack,” in which an artery supplying blood to the heart-muscle is suddenly occluded. The severity of the attack depends upon the extent and rapidity of the disruption of blood supply; but all too often, this first indication of coronary-artery disease terminates rapidly in death.
