As f...Not sure what you mean in the first comment.<br /><br />As for the second, I think the computer's measurement of 138 ms is correct. However, if it were a short PR, then one must consider LGL but there can also be accelerated AV conduction.Steve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-19125362144039234442011-06-11T13:41:36.048-05:002011-06-11T13:41:36.048-05:00Dr. Smith,

Hopefully your equation for differenciating BER to anterior STEMI gets in there as well.<br /><br />Also for this strip, I have the PR interval at or slightly less than .12 even in the presence of a prolonged p-wave in II (which I've been told is indicitive of RAE?) which would lean towards an LGL syndrome right? Besides the obvious MI.Troyhttps://www.blogger.com/profile/01227334538616584664noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-44310498756588361542011-06-11T09:00:28.508-05:002011-06-11T09:00:28.508-05:00I think you are right about this: no reciprocal ST...I think you are right about this: no reciprocal ST depression. However, 50% of anterior STEMI does not have reciprocal ST depression in inferior leads, and inferior MI, when it is simultaneous with lateral STEMI (and ONLY when simultaneous with lateral STEMI!), may not have recriprocal ST depression in aVL. In this case there is simultaneous antero-infero-lateral MI.Steve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-6965444666346536712011-06-11T08:14:07.098-05:002011-06-11T08:14:07.098-05:00I wonder if the machine isn't interpreting it ...I wonder if the machine isn't interpreting it as an MI due to no reciprocal changes (not counting aVR). Sadly some hospitals in my area won't accept a STEMI alert unless the LP12 interprets it as a **Acute MI**.Troyhttps://www.blogger.com/profile/01227334538616584664noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-49521909938894206162011-03-09T16:13:14.873-06:002011-03-09T16:13:14.873-06:00i've noticed that LP12s love to interpret VT, ...i've noticed that LP12s love to interpret VT, even very obvious VTs, as a-flutter. even worse, people actually believe the auto-interpretation and fail to treat!<br /><br />which brings us back to what you said: humans must learn how to read a 12-lead properly.burned-out medichttp://burnedoutmedic.comnoreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-19723761650320030802011-03-07T21:43:58.763-06:002011-03-07T21:43:58.763-06:00Yes, but that's not the point.
