I'm sorry you haven't had any comments on this post. I try and keep quiet unless I have something of value to offer.
WPW is a form of AVRT; accessory pathways. These are located in the atrioventricular valvular rings. They provide a direct connection between the atria and ventricles. Accessory pathways that give rise to WPW syndrome and AVRT are located in the atrioventricular valvular rings. Individuals with Wolff Parkinson White have an accessory pathway known as the bundle of Kent. This accessory pathway does not share the pulse-slowing properties of the AV node. This is a bundle of connecting tissue that may be
either between the left atrium and the left ventricle, in which case it is termed a type A pre-excitation, or the right atrium and the right ventricle, in which case it is termed a type B pre-excitation. Type A is the more prevalent, hence the transseptal approach the was done on you back in 2000 (and on me just 3 months ago).
AVNRT involves a reentry circuit which forms within or right next to the atrioventricular node. The circuit usually involves two anatomical pathways; a fast pathway and a slow pathway, which are both in the RIGHT atrium. The slow pathway is usually targeted for ablation. These pathways are formed from tissue and exhibit behavior very much like the AV node.
The question is can an indivdual have both AVRT and AVNRT as you were apparently diagnosed with? Personally, I have no clue and which is why I hesitated to give a response. I can tell you that although I was first diagnosed with WPW, it turned out that I had another form of AVRT called Circular Movement Tachycardia (CMT), a persistent form of SVT.
As a comparison to your figures at the bottom of your post, here were mine from a followup visit to the EP 1 month post ablation:
Vent. Rate: 82bpm
PR interval: 142ms
QRS Duration: 84ms
P-R-T axes: 40 28 23
As a reference, I'm a at the other end of the height scale at 5' 7" and I'm 60 years of age. I don't know if this is of any help to you, but I thought I'd offer it up.
Actually now that I think about it I'm pretty sure the 2nd discharge notes said "AVRT" which makes a lot more sense really when I think about it.
Most what I'm concerned about now are the PAC's and how they relate to my previous history. As near as I can ascertain they have NO bearing whatsoever.
I didn't realize this at the time of my ER visit the other night, but the next day I woke up with a horrible head cold and in some of the diff. diagnosis for PAC's that I've seen it lists "infection" as a possible cause so I'm wondering if it as just as simple as that, or the borderline Mag level or a combination of both.
Like I said I've had these things before off and on and just blew them off or perhaps didn't even notice them. Apparently 50-60 percent of healthy people put on a Holter will have ectopic beats in a 24 hour period without even knowing they are having them.
