Why the study?
Does the analysis of high-frequency components (notching) in orthogonal ECG leads help localize the site of myocardial scarring compared to autopsy findings?

High-frequency ECG notching in specific orthogonal leads can help diagnose and localize intramural myocardial scarring even when classic ECG criteria are absent.
No takes yet. Share an insight, caveat, or question.
May aid scar localization in normal hearts lacking classic ECG signs; hypothesis-generating and should not change practice.
Flowers et al. (1969) studied this question.
