WebAnother indicator of ischemia is T wave inversion. T waves are normally a positively deflected waveform. In some cases of ischemia, the T wave will become negatively deflected. T wave inversion may be seen by itself as shown in Figure 14-10. Most often T wave inversion is seen with concurrent ST segment elevation (Figure 14-11). WebHowever, T-wave inversions in the lateral leads are confined to males and have been identified in only 0.3%. 11, 14, 15 In contrast, T-wave inversions are identified in 10% of black athletes (6% inferior leads and 4% lateral leads) but as with caucasian athletes, T-wave inversion in the lateral leads is usually absent in black female athletes. biogen north wales
