Abstract :
Changes in body position are sometimes mistaken for myocardial ischemia during ECG monitoring in the coronary care unit. Two different methods for detecting body position changes based on spatial and scalar approaches are investigated. These methods have been tested in two databases containing controlled body position changes, and ischemic episodes, respectively. The results show that reliable detection is possible in more than 90% of the cases
