Isn't it pretty rare to have a tachycardic block ? Would it be fair to say that this could usually only be pharmacological (Digoxin) as opposed to structural ?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4505990433916682663.post-6864168439404564942009-05-16T23:16:00.000-04:002009-05-16T23:16:00.000-04:00The P waves seem obvious to me, but that was becau...The P waves seem obvious to me, but that was because I saw the title and looked and found the P waves in the first strip. If I had this call, I wonder if I too would not consider expecting to find a heart block in a tachycardic patient. I hate to admit it, but on a late at night or after the umpteenth call, would consider it just a LBBB and do the same with it. All the reason to avoid tunnel vision.Shaggyhttps://www.blogger.com/profile/10687847155700323439noreply@blogger.comtag:blogger.com,1999:blog-4505990433916682663.post-87942655800021297422009-05-08T09:45:00.000-04:002009-05-08T09:45:00.000-04:00Found this strip laying in the front of the ambula...Found this strip laying in the front of the ambulance. I'm pretty sure the medic who left it didn't notice the 2:1 conduction. He probably did what so many do and called it a LBBB, and threw it away.Adam Thompson, EMT-Phttps://www.blogger.com/profile/18107359165856983910noreply@blogger.comtag:blogger.com,1999:blog-4505990433916682663.post-9949563009750564052009-05-08T00:37:00.000-04:002009-05-08T00:37:00.000-04:00Nice catch.

V2 ...Nice catch. It is hard to notice without V1. <br /><br />V2 has a more subtle P wave on the T wave. <br /><br />Much harder to notice in leads II and III. <br /><br />Few people would look for a heart block in a tachycardic patient.Rogue Medichttps://www.blogger.com/profile/07598646309630074992noreply@blogger.com
