Smith SW et al. Diagnosis of ST-Elevation Myocardial Infarction in the Presence of Left Bundle Branch Block With the ST-Elevation to S-Wave Ratio in a Modified Sgarbossa Rule
There is one rather glaring, but inconsequential, error in the article. I'm interested to see if you pick up on it, so I won't say what it is yet.
And, of course, we will publish an erratum later, unless there is a letter to the editor to which we will respond.

All I noted was that Fig3a calculated the ST/S ratio to be "2/23=0.087", which should be 2/-23=-0.087 if the S-wave depth measurements are to be kept consistent. Fig3b uses the consistent S-wave depth notation (i.e. negative millimeters).
ReplyDeleteI had not noticed that one!
ReplyDeleteInteresting article, dr Smith!
ReplyDeleteI'm not sure what the inconsequential error is.. Could it be that you called the measured proportion "ST/S ratio" although you actually measured the ST/R ratio in the leads were the QRS-complexes were positive?
One question.. Isn't de Winter T-waves considered to be a STEMI equivalent?
No, that is not the error.
DeleteAs for de Winter's waves: yes, they happen with LAD occlusion and are definitely STEMI-equivalents
Thanks,

Has this been peer reviewed yet
ReplyDeleteof course. that's why it is published in Annals.
