Nonspecific: The t wave is more commonly upright in those leads; when it is upside down (a negative deflection), it is inverted. T wave inversion in leads iii and avf can represent normal findings, but in the appropriate clinical setting, can indicate that further evaluation of the heart is needed.
Web26 mei 2024 · By multivariable analysis, inverted T wave was an independent predictor of the composite cardiac endpoint (HR 1.53, 95% CI 1.26 to 1.85, p<0.01). Inverted T wave was detected in 15.7% at anterior leads, 19.8% at inferior leads and 26.6% at lateral leads. The location of inverted T wave was not associated with risk of composite cardiac endpoint. 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.
Web7 apr. 2024 · T-wave inversion (TWI) is defined as negative T-wave of ≥1 mm in depth in two or more contiguous leads, with exclusion of leads aVR, III, and V1. 1 The presence of TWI at 12-lead electrocardiogram (ECG) in competitive athletes is one of the major diagnostic challenges for sports physicians and consulting cardiologists.
