ST analysis of Holter tapes.
In recent years, it has become increasingly clear that for an important subset of patients with coronary artery disease, many or all of their ischemic episodes are not accompanied by anginal pain. For these patients, it is desirable to detect these ischemic episodes as periods of ST-segment depression on Holter tapes. In the past, such detection has been difficult because the analysis methods were artifact-sensitive and failed to differentiate ischemic from nonischemic ST-segment changes. This work describes a new ST-segment analysis algorithm that has been added to the existing computer-based Holter analysis system. This system is highly artifact-resistant and has been designed to minimize the loss of processing speed while maintaining extremely high accuracy.
