I'd like to first thank anyone who can give me some clarity and thank you in advance. Because I'm scared out of my mind right now.

What occurred no more than 45min ago as I was sitting in a class, has happened before. I had one of these attacks as I'll call it last year around October maybe? The one previously was 6+ month prior. They usually occurred at night.

Well not this time, and this was possibly the worst one yet. I felt like I was going to die because of how my body was reacting. It started with a tough time breathing. And not that I was struggling to suck in air, it was just like my throat or maybe the chest was constricted in some way, but didn't 'feel' like it if that makes sense. After a little while of the breathing problems, I suddenly get this odd feeling come across my body. Almost as if the blood had been drained out of me and it's just so difficult to describe what this feeling is. This feeling like the previous times, results to the next stage. And that is HUGE heart beat increase out of no where. This last maybe a few minutes( the max speed of it ) then it slows down big time, almost to point where I feel like it's going to stop since it's so slow. Then it goes back to a regular, but still elevated heart rate. I then feel very weak after it, I have some problems being able to speak as I feel so drained and my hands are shaking a bit ( I assume from the adrenaline being pumped as I am panicking of course. )

And that is usually it, I will recover, feel very odd like I just suffered a heart attack or something as my body has this feeling like I just recovered from some severe trauma ( which it basically it did in my mind ).

This time was quite worse as after the initial attack, and my heart rate slowed down, it started to raise again and I got the same weird feeling inside my gut almost as if it was going to give me the same attack again. It luckily didn't go as bad as the first one. After that I started to recover, still feeling odd inside and my pulse still a little bit elevated. I'm now at home 45min later, feeling better. My pulse is still a tad high, not much and I feel bit strange inside still, but I'm better.

Is this just panic attacks or anxiety? Or are these signs of something else? I wen't in before ( many years ago ) about this issue and my heart checked out alright and I've had ekg monitor once years ago that showed nothing. Things could show different now, who knows. But does this sound like Anxiety/Panic attacks or is it something else?

Any help to ease my mind, I'd so greatly appreciate it.

Do you get restless or uneasy right before you have trouble breathing? I would feel really weird(sometimes for hours) then before I knew it I couldn't breathe, my heart would race and beat hard against my chest. Then like you said it would just go away. Sometimes my heart would slow down so suddenly I would get a heavy feeling in my chest. The doctors called it an anxiety disorder and over the years I've learned to control it to the point where I no longer need medication. Don't just take my word for it though, you should consult a physician to make sure there isn't something more serious going on. But whatever you do don't freak out--it only makes it worse. Good luck.

Thanks for the reply.

I can't say I get restless, an uneasy feeling I can't seem to recall. I think the uneasy feeling I did acquire was simply from the result of the first stage of the breathing change. It alerts me that something is wrong. It's always sudden, some type of breathing issue where I'm breathing normally but it seems a bit more difficult or constricted, even though my throat and chest are fine. Then that odd feeling I discussed takes over my body, as if it's preparing for something terrible. It's as if you were to get a lot of blood drawn and you have that loss of blood feeling, sort of a chill and light head which shortly hits with the huge increase of my heartr rate. 30 seconds to minute later it drops down to really low just suddenly, as if it's going to stop and then goes back to semi-normal, but still quite elevated ( say, 90-100 and my resting is 55-60 ) for an hour or so after.

After it, for hours I will feel like my chest is bruised and still feel odd. Even right now I don't feel 100%. Feels as if my inside of my chest or heart is bruised.

I had hoped that it was anxiety or a panic attack. The problem is, I feel since it only occurs 1-2 times a year and the severity of it is so great, I couldn't possibly think it would be so easy as being that.

I have found something called Supraventricular Tachycardia

"Supraventricular tachycardia (SVT) means that from time to time your heart beats very fast for a reason other than exercise, high fever, or stress. During an episode of SVT, the heart?s electrical system doesn't work right, causing the heart to beat very fast. The heart beats at least 100 beats per minute and may reach 300 beats per minute. After treatment or on its own, the heart usually returns to a normal rate of 60 to 100 beats a minute."

This unfortunately seems right up my lane. I have a GP appointment on Wed. and will get a re feral to a specialist. I wish so hard this was anxiety or panic disorder, but it seems to severe and more on the line of this electrical system issue, sadly.

I had the same feeling of my heart racing and feeling like someone pulled a plug and my blood was being drained out of my body. Almost feeling like I was being pushed down from my head. My doctor said it was a combination of an anxiety attack and my blood pressure going too high. My father had just passed away a week before and I ended up in the ER with this feeling. After the doctor got me on bp meds and some xanax I was doing fine for a while. about a year and 1/2 later it happened again while I was at work.. but this time, my blood pressure was too low. So the doctor adjusted my bp meds again and I am doing fine for the most part, almost 4 years later. Every now and then I get my heart racing and my face feels like it is burning up.. but after a xanax and some more water, I lie down for about an hour and it is ok. But yes.. I panic about the feeling and it makes it last longer. It's like the more I think about it the more often I have the attacks. Oh year.. the other thing is, I notice it happens a lot more often if I didn't get enough sleep the night before. Hope all is well with everyone now!!!

Hi Notasf_n,

Welcome to HealingWell.

Look forward to seeing your posts, anxiety and heart rhythm issues have plagued me much of my life. It's amazing how much anxiety and stress effect our heart rhythms, blood pressure, and much more.

Be well.

i used to suffer full blown anxiety attacks cry sad and would have your breathing symtoms, racing heart, multiple runs of PVCs, and this happened once when I was stuck in traffic. I thought I was going to die. I felt like jumping out of my car, and screaming/gasping for help. I could not catch my breath. Hyperventilating made it seem worse,
and then, after a minute, or a long 2 minutes, whatever mechanism took over,returned me to some sort of calm. I then went on xanax for awhile, then was put on Klonopin. Since then, years have passed by and no full blown anxiety attacks have occured. but, like JungRule,
I have been plagued with rhythm disorders for many years. I find support and comfort here and I hope you do too.

Welcome new members, you have a good forum here

best to you :-)

Shasta13: You've described perfectly what I wasn't able to! I've had this happen twice to me in the past two weeks. At first I thought it was because I was on a new medication, but now I'm not so sure. Because if I can recall, this happened to me a few months back as well. I see you haven't been back in this forum in about a year, but if you see this could you please tell me if you ever found out what was causing it?

And if anybody has any idea what it is, please message me. But if you think it's from panic attacks/anxiety don't bother replying lol because it is definitely not that.

I've had svt since birth, It also causes silent heart attacks, Before my last surgery I found out I've had two & because of the svt my heart muscles are extremely weak, they should be 90-100 mine is 20-30, because of the daily racing. I'm on 3 meds and one is a heart failure medication, It does sound like svt to me honestly, I had the same feelings before & when I went to the er they said it was my heart triggering another silent heart attack, thank god I was there. I just had one of the attacks as you call them just now, which by now I've learned for me at least it's the sign of a silent heart attack, Thanks to my heart doctor telling me what to expect. I hope you get the help you need I recommend propefano, I'm not sure on the spelling, but that and Lisinopril they have helped big time. Lisinopril is for heart failure, Because mine has gone on for many years my heart is very weak, I hope they can catch it before you get to the point where I am, it's god awful and I wouldn't wish anyone to go through this.

By any chance, do you recall taking aspirin and drinking coffee or coke around the time you had these episodes?

I had the same thing as you described (with the addition of a full collapse onto the floor) and come to find that I had an allergic reaction to the aspirin which produces neurological symptoms. The caffeine then blasted the symptoms into orbit.

I found this out about a year later by taking Excedrin. Excedrin is basically aspirin and caffeine wrapped into a nice little pill and triggered the episode again.

I've had many panic attacks throughout my life, as I was diagnosed with Generalized Anxiety Disorder when I was 17. I definitely had the same feelings you had and they were terrifying. My heart would race, my chest would hurt, and I felt as if I was "outside of my body". These are all symptoms of panic attacks. However, if you have not seen a cardiologist I would suggest you do so. If everything comes back normal, at least you will have peace of mind. SVT can cause identical symptoms. Generally, SVT will cause your heart to race very fast and you may feel lightheaded, faint, or sweat. When SVT occurs, it usually only lasts a few minutes; however, some people may experience SVT for longer periods of time. If you are young and otherwise healthy, SVT is almost never life-threatening. It can be very scary though! If you do have SVT, you said it has only happened once or twice a year. My guess is that a cardiologist would not even put you on medications, as your episodes are very infrequent. You would probably be instructed to perform Vagal maneuvers (coughing, splashing your face with cold water, etc.). These maneuvers can slow your heart rate down. At the most, a cardiologist may prescribe a medication (such as a beta blocker) that you can take when you experience the episodes. When people have frequent SVT, sometimes catheter ablation is necessary. Catheter ablation is a procedure where a tiny part of the heart is destroyed in order to permanently stop the SVT .

In addition to making an appointment with a cardiologist, I would suggest you make an appointment with a psychologist or psychiatric nurse practitioner. Even if you end up not having anxiety, these professionals can give your their advice and input on what they think these episodes are. I suggested a psychiatric nurse practitioner, because I really don't think your case is severe enough to warrant a visit to a psychiatrist (not to mention they can be incredibly hard to get into). I understand what you're going through and it can be frightening. I have had two echocardiograms, numerous EKGs, a 30 day event monitor, and a stress test. I have had one brief episode of SVT, otherwise my fast heart rate has been due to sinus tachycardia (a completely normal fast heart rate). Please let me know if you have any questions and I wish you the best!

Slee17, just so you know, you have commented on a very old thread & Shasta has not been here in almost 3 years. This forum is a not a busy forum with many old threads & not many active members. You can click on a members name & it will show you when they last posted. By chance do you work in the medical field?
