Development of a template boundary algorithm to determine the ST-T threshold for silent ischemia.
A template boundary algorithm which quantitatively determines ST-T variability has been implemented and tested using seven normal patients. Relatively uniform variability was demonstrated throughout the ST-T segment in these patients during single lead continuous electrocardiographic monitoring at bedrest. The range of variability appears to be a function of both R wave and T wave amplitude. This algorithm appears to have potential utility in defining the ischemic criteria for silent ischemia.
