Webleads V3 and V4, is termed an isolated T wave inversion or isolated T wave negativity (1,2). Such isolated T wave inver-sions are most frequently seen in patients with angina pectoris, especially in those with unstable angina. Isolated T wave inversion also occurs in healthy individuals with no evidence of heart disease (3-5).
