Animal data link repolarization to ST shifts in injury; leaves open translation to human ECG diagnostics.
What is the electrophysiological mechanism underlying S-T segment alteration during acute myocardial injury?
S-T segment shifts during acute myocardial injury are primarily driven by rapid repolarization of injured cells, while T-Q changes are driven by decreased resting potentials.
Samson et al. (1960) studied this question.
