For this reason — Adenosine should be used with caution in patients with known WPW, given theoretic possibility of inducing AFib (which could have significant consequence in a patient with accessory pathways)". Thanks a lot again Drs Gen Grauer and Smith.

The best pharma treatment for atrial fib is propafenone. Try that.<br />3. It takes a minimal amount of propofol to provide amnesia for the cardioversion. just cardiovert.<br />4. That's a good idea!<br />SteveSteve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-82033517483558305102016-03-29T09:10:44.762-05:002016-03-29T09:10:44.762-05:00Steve,

I believe it might have been removed as an option in the American guidelines, but it remains in the European guidelines (although I question it's safety due to the partial AV nodal blocker effect). Where I work we don't have neither procainamide nor ibutilide.<br />2. Do you think vernakalant would work and would it be safe?<br />3. How would you manage a stable patient with preexcited Afib that you've decided to sedate and DC cardiovert, in a situation where the patient just had a meal. Is it safe to wait a couple of hours with the patient closely monitored (thereby limiting the risk of aspiration) or would you sedate and shock the patient anyway?<br />4. Do you know anything of giving calcium channel blockers (i.e. verapamil) to patients with a suspected concealed pathway (patients that report frequent palpitations who has a short PR interval) as a diagnostic challenge? It would potentially be a nice way to reveal the delta waves.P Hammarlundhttps://www.blogger.com/profile/12795866723817205360noreply@blogger.com
