Unless externalization is associated with dysfunction, it may not have much significance.<br /><br />I'Jayhttps://www.blogger.com/profile/10897176780069403370noreply@blogger.comtag:blogger.com,1999:blog-18943510.post-67213027006408265332012-04-04T13:27:21.915-05:002012-04-04T13:27:21.915-05:00mcg-

However, imaging (by way of fluoro or careful xray exam) may be the only way we can determine the full extent of this problem for our patients clinically.

Maybe routine fluoroscopy is indicated.. also, I don't understand how pacing impedance is not affected, could you explain this?mcgnoreply@blogger.com
