What is NSVT?

[mabebesc]

I keep reading about NSVT and numbers following it.  Can you tell me what it is?  Does it feel like SVT  it doesn't last as long?  I've just been ablated for AVNRT so that's the only arrythmia I am really familiar with? I'm guessing it stands for nonsustained ventricular tachycardia and the numbers sstand for how mnay beats you get. Thanks!

Hi. NSVT is short duration VT and it shows up on an ecg. The categories are:

Idiopathic VT is VT that has no defined cause.

Monomorphic VT has a more or less constant shape on the ecg on a beat per beat basis. (i.e the morphology is thought to not change, or to have single origin).

Polymorphic VT has an ecg shape that changes with time, ie.the morphology changes or is said "to have more than one origin". However, I would think that having polymorphic VT would actually suggest that something is changing in the cardiac tissue (which would cause conduction wavefront to vary in shape, magnitude, or direction of travel) each beat.

SVT refers to Supra-ventricular tachy. Supra being above the ventricles ie. the atria. So it could be atrial tachy or atrial flutter or even a-fib I suppose.

Someone posted this awhile back and I just went back to search YouTube for the video....It's so cool!!  You guys are gonna love this demo!  This doctor demonstrates the way different arrythmias feel (using his arms, legs, body)!!  SO COOL!!

You're exactly right! Its basically a bunch of pvc's in a row, with no normal beats in between. I get several "runs" a day. They are scary! As for the svt, I don't have that so I don't know what that feels like. I've wondered that very question, though, as it seems some people on here say they feel the same.

Hi Betty-

You're too funny...You answered your own question *LOL*

Did you fly the coop today? I am still here nursing a stiff neck. I saw my PCP yesterday and was given flexaril and Ibuprofen 600mg. Hopefully I will be feeling better by tomorrow.
