A long-term ST database for development and evaluation of ischemia detectors

Reports the status of an ongoing international collaborative research effort to produce a new long term ST database (LTST DB), a collection of seventy annotated ambulatory records containing transient ischemic and non-ischemic ST changes. The authors present the selection criteria for records, an annotation protocol with definitions of transient ST events, interactive graphic tools for manual and automatic annotating, and the annotation procedure.
