WebT-wave inversion on ECG is usually a concerning finding as it is often associated with myocardial ischaemia or ventricular strain. The respiratory variation in the T-wave morphology has been reported in the literature, 1 however the frequency of this observation remains unknown as this is not routinely evaluated. WebNew T-wave inversions. The T-wave is the last wave in the pattern, with the U-point marking the end of the T-wave, after which the pattern starts over again at the next heartbeat’s P-point. New T-wave inversion means that if your T-waves normally curve upward (like a hill), they now curve downward (like a bowl). Lab testing

WebT wave inversions in the right chest leads may be caused by right ventricular overload (e.g., acute or chronic pulmonary embolism) and in the left chest leads by left ventricular overload (Chapter 7). Diffusely inverted T waves are seen during the evolving phase of pericarditis or myocarditis. WebWhen the wave hits the fixed end, it changes direction, returning to its source. As it is reflected, the wave experiences an inversion, which means that it flips vertically. If a wave hits the fixed end with a crest, it will return as a trough, and vice versa (Henderson 2015). Refer to Figure 13.17.
