svt with aberrancy and Fusion pvcs.

Hello everyone.  It has been a while since I have been on this site. I really hope everyone is doing wonderful!   I recently wore a 30 day event monitor (mostly for peace of mind as my echo and stress test were normal).  Upon reviewing the results with my EP, I was told there was nothing to worry about.  When I asked him about one specific episode that felt as if my heart was beating very irregular for a few beats he told me that it was Atrial Tachycardia with abberancy.  Well I guess I should have had him explain that better to me because when I went home and looked it up I see that it always is associated with VT?????    Now all he said was the heart might have been trying to go into AFIb but your heart wouldn't let it.  Does anyone have experience with this?  I would like to post the strip but I am not sure how to do that either.
I also imagine that if it was really VT that I would have been notified right away.

Second....When I first started one of my runs I apparently had a few "fusion" PVCS.   I was also told that it was nothing to worry about.  Anyone know about those?  (that was auto triggered).

Please let me know...my history is PSVT  (rare.  Haven't had a real run in years but I still get short bursts sometimes).  However this one episode of the uneven heart beats did not feel like my burst of PSVT.  I also have had PACS and PVCS but again probably not more than 300 a day ever showed up on any of my holters.

Thank YOU!!!

From what I understand, even short runs of vt are not a big concern if the heart is healthy.  the heart will be able to correct itself so if the doctor isn't all that concerned I would not be.  I also wonder how something atrial can be always associated with VT which is a ventricle issue.  I think you may have misunderstood.  The doctor said Atrial Tachycardia not Ventricular Tachycardia and the article you read was likely related to Ventricular tachycardia.  It can be very confusing considering the terms can sound very similar.  I would try to not worry about it all and just keep an eye on the svt.  If it gets more persistent consider an ablation.    Other than that stay well hydrated and avoid sugar and caffeine and see if it helps your premature beats.
Hey Michelle - Yes the doctor did say Atrial Tachycardia, that in itself wouldn't have concerned me as it was a very short run.  But he added the "with aberrancy".  That makes a difference when you google (SVT or SVT with aberrancy) because when people are presented in the ER thinking it is VT, it sometimes is actually SVT with aberrancy.  Something to do with the QRS wave being larger with aberrancy and making it look similar to VT.  It also says you need to look for a p wave and if there is one it isn't VT.  Anyway you are right, he shook my hand and told me I was fine.  I need to stop digging deeper into this.  I was hoping someone else actually was diagnosed with it and had a good understanding of it.  Thanks for answering.  
My doctor called and explained it.  I will keep it here in case anyone else every is told they have svt with aberrancy.
Atrial tachycardia with aberrancy just means that the bottom chamber of the heart (ventricles) responded to how fast your top chambers (atria) were going, and created a different-appearing rhythm on the EKG. However, we know this is not VT as there are certain criteria for the morphology, onset, and stability of the rhythm that were not met for consideration of VT. So that is why it feels a little different. Somehow the signal from the artia gets stuck in either the LBBB or RBBB. So the ventricle sends it out differently. Thus the more irregular beats versus just the fast quick bursts I usually feel with SVT.
