Quantitative evaluation of treadmill test induced ST-T changes using body surface mapping.
Using the ST difference map after the treadmill exercise test, the 26 patients with coronary artery disease were studied. 1) The extent and the speed of complete recovery of ST depression or negative area were well correlated with the severity of coronary artery disease. 2) ST elevation or positive area was correlated with regional asynergies. 3) ST elevation area disclosed regional defect of 201 T1 scintigram at rest, while ST depression area could disclose it infrequently.
