Early Repolarization vs LAD Occlusion

  1. Thanks for this. Dr Smith, do you have any case with fish-hook J point which proved to be Ischaemic?

  3. Very nice study. I'm alittle confused with your method of measuring the ST segment elevation (whether it be for a STEMI or early repolarization). Is it the J-point plus 40ms (which is what I've seen in many texts and articles? Or is it the J-point plus 60ms like you said? Do you use one method for one situation, and the other for another?

  4. In the study, we measured STE at the J-point AND at 60 ms after the J-point, both relative to the PR segment. It would have been better to measure STE at Jpoint relative to PR, and at 60 ms after the Jpoint relative to TP; but that's not what we did. We also measured the T-wave amplitude, R-wave amplitude, and QTc. Then analyzed to see which are best.
