There are two previous papers on use of sgarbossa criteria in paced rhythm, but both with very few cases. I nevertheless think it is safe to treat paced rhythm like LBBB and have few cases here on my blog which illustrate STEMI in paced rhythm.<br />SteveSteve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-17684019723991611882013-12-05T15:01:25.124-06:002013-12-05T15:01:25.124-06:00Hello Dr. Smith,

Therefore, a positive modified Sgarbossa criteria would still have a low post test probability, but the consequences of missing the diagnosis are severe, so a false + is not so bad. The post test prob of a negative mod Sgarbossa would be incredibly low and all but rule out occlusion<br />Steve SmithSteve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-28800462094179710892013-11-03T10:41:43.323-06:002013-11-03T10:41:43.323-06:00I have read this full text,
