摘要：
A system for the detection of cardiac events occurring in a human patient is disclosed to include at least two electrodes for obtaining an electrical signal from a patients heart. At least two electrodes are included in the system for obtaining an electrical signal from a patients heart. An electrical signal processor is electrically coupled to the electrodes for processing the electrical signal. The system determines the presence of a cardiovascular condition by applying a sliding scale rule to heart signal feature values. When the cardiovascular condition is ischemia, the ST segment may be analyzed. A sliding scale is applied to ST segment shifts such that when the magnitudes of ST segment shifts are relatively small, a larger number of beats is required to detect ischemia compared to the case when the magnitudes of ST shifts are large.
