[HSF] A. Fib. Surgery: How to Assess Success?

[Tea Acuff]

Yes it would be the best way to evaluate rhythm. But as Dr. Cox recently reminded us we don't actually know what "normals" have under the same monitoring. Be sure to included one or two set of "controls". Don't compare it to your "imagined normal".

I'm going to talk to one of our senior Medtronic reps tomorrow (I have a
port-access epicardial BiV upgrade with them in the afternoon, following an
AVR at another hospital). As you know, the Reveal is about 6x2x1 cm and is
implanted subcutaneously, with no additional wires. It lasts around 14
months and can hold a total of 40 minutes or so of recorded EKG. I believe
that there are two programmable data collection modes - patient activated
and automatic, with programmable parameters for brady or tachy events. I'll
get more information on this.
