I think ST segment seems to follow PR curve and as far as I could see PQ junction and J point is at the same level.

The way you phrased it reminded me of that old adage. On a more serious note, however, I am curious what portion of Inferior MI's would result in an aneurysm vs. and Anterior or Lateral wall MI. My impression was that the latter are more common. Not sure on the incidence of aneurysm post DMI.Anonymoushttps://www.blogger.com/profile/06881621536276162248noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-89232556360070565122013-01-20T11:56:22.249-06:002013-01-20T11:56:22.249-06:00Yes.
