WHAT Waveform changes is most closely associated with tissue injury?

The waveform changes most closely associated with tissue injury are typically an increase in the amplitude and a shift in the morphology of the electrical signals observed in an electrocardiogram (ECG) or other monitoring devices. Specifically, in the case of myocardial injury, there may be ST-segment elevation or depression, T-wave inversion, and the presence of abnormal Q waves. These changes indicate impaired electrical activity due to necrosis or inflammation in the affected tissue.
