supraventricular tachycardia

So for about a week I been feeling what I thought was a PAC's and still could be I guess..
I had a 24 hour heart monitor on that I returned yesterday.
I woke up to my phone ringing and the nurse from my regular physician told me the results.
She said, we got the results back and it looked like you have some SVT runs on your monitor, the Dr would like
you to have a Echo stress test and follow up with a cardiologist.

WTF WTF WTF is going on, those were my thoughts and it shot me into panic....
I had no idea what SVT was so I thought immediately I was gonna die soon.
I found out its supraventricular tachycardia and that I had a total of 160 beats on my 24 hour monitor, and one run of 16 beats.
Not sure if that is a lot or pretty normal for SVT, I was told its benign condition and there is up to
3 million cases a year and it is not LIFE THREATENING.

If this is what I have been feeling its very fast and only last 3-4 seconds usually but happens quite frequently.
Can SVT be that quit onset and off?

My Dr gave me some beta blockers to take, I have not taken them yet. 50mg of toprol (metoprolol) to take one
time daily.
I'm already taking blood pressure meds but he said to take both...WTF won't that make my BP way to low.
My normal reading is 120/65 pulse usually 59-65.
If I remember correctly my pac count was around 100 and my pvc was around 20.

All this is a lot to take in and I'm pretty scared at this point.
So here is my questions.

Who has SVT (PSVT) and how long have you had it?
Did you get ablation?
Have you tried beta blockers for it?
Did it work? How do they work?
Can I exercise with SVT?
Why did the Dr. call me so fast if its not dangerous?
Why did they set me up to have a echo stress test?
Should I be this worried?

Sorry for all this and thanks a ton for all the help, this board has already helped me a ton.

Usually the way they tell if it is an svt or simply sinus tachycardia is if there is a wave missing.  In regular sinus tachycardia all the proper waves are there it is just a fast beat.  Sometimes svt can mimic sinus tachycardia so doctors will usually diagnose it if they see the fast rate start and/or stop in one beat.  That is usually the best way to tell.  If it was just a tech reading it is possible that the cardiologist will change the diagnosis but for your knowledge 1% means only 1% of your beats were associated with the issue so very minimal.  For you it was less than 1% which could mean only a couple of beats.  

Also for your peace of mind my cardiologist said it is unheard of for someone to drop dead from anything in the atria.  That doesn't mean it can't happen but odds are very slim that it will.  Even afib is not an immediate threat.  The biggest threat with afib is when a person goes back into normal sinus rhythm there is a chance they may throw a clot and have issues from that.  Atrial issues generally are long term issues that threaten heart failure but usually only after an extended period of time meaning years and years with the issue if it is intermittent.  A constant rate well into the 200s is a danger if left untreated for days but in a younger heart if any of it is intermittent the heart has plenty of time to recover.  Basically the doctor told me that we really don't technically need the atria.  I am sure that was just an exaggeration but in terms of our well being they pose little threat to us when things go wrong with them unless the ventricles are involved.  But even still a lot of things have to line up for any heart rhythm issue to cause sudden death.  It is a lot rarer than you are fearing. Honestly, the stress and anxiety will do you in sooner than any heart issue so it is important you work on that.

In any event, I understand about wanting to be informed but try to use the information to look at things objectively.  I know it can be hard when you have anxiety but just try to stop the fear thought train and take deep breaths and calm yourself.  This will get easier to do the more you do it.  Take care and put some extra focus on your child and less on your heart and see if that helps.  Hang in there.  It's going to be OK.

I'm confused about difference between svt and afib? When in afib one has svt ? I have persistent afib or did before my ablation 3 weeks ago.....after ablation do the symptoms change if they come back as in less or is it all or nothing?

I was just wondering how is your leg(s) feeling after the weekend?  Still sore?  I recall noticeably limping for about a week after mine.  Have you had time to digest what has all gone down, and do you have any idea of your next move?  I hope you're feeling better!

It wasn't really that bad, I was awake the whole time but on medication to keep me calm and it was good stuff, after they tried for a without adrenaline and not getting it they added adrenaline and they basically made my heart go crazy with pacs/pvcs, you know when you feel one pvc, its like that but they are way harder feeling in the chest, I couldn't take much more of the adrenaline and then they finally stopped it as I was thinking about telling them to stop.

I don't know what to think right now about the whole thing and I'm not sure were to go from here with my life.

Sorry to hear it didn't work out this time. Can you give us the play-by-play of the ablation? It sounds like you were awake the whole time. Was it really uncomfortable when they were pacing you? Did they rev your heart up with adrenaline? Could you feel the pacs/pvcs they were creating while they tried to induce the SVT?

That part of it always sounded nerve wrecking to me. I have SVT (AVNRT) and it's somewhat controlled with medication but I think I'll eventually need an ablation.

Thanks Tom and Michelle, the Dr really put my heart through the paces trying to get my SVT to start.
Right now I'm not taking any meds and am dealing with it, I have not felt it still (knock on wood) is is possible that I just had some episodes that may not ever return and it fixed itself?
Is there a pill to take just when I have episodes?
On my heart holter, I was told I had a total of 160 SVT beats and 16 beats were the longest run.
While waiting for the staff to come get me for my ablation I told them I was just gonna re-schedule and that I could not wait any longer, the Dr came in and talked with me, he looked at my chart and said there is some SVT runs and its not isolated beats, he said we could always try the ablation or meds and its my choice.
At the time it was happening daily, everytime I sat down I would have a small run of SVT.
After all the tests I have done, what else could it be?

I just hope it fades out and never comes back, but if it does and sticks I will have to do the ablation again I guess.
