Did I do something to my heart?

I have just managed to find a way to get my heart rate right up higher then I have ever done before. My heart rate monitor tells me its at somewhere between 93 to 98% (around 175 to 185bpm, I am 28 and female.) for part of my workout, I cant sustain it for very long so have encorporated it into a sort of interval training where I do 1 min on 1 min off, throughout that my heart rate doesn't go below 74% (which is about 145bpm). I do this in 20 min bouts and take about 1.5 to 2 hours a session with about 3 or 4 of these included and then stretch and cool down afterwards.

I have though been noticing its much harder to fall asleep, already I have insomnia and take about an hour to settle, but since doing this its been about 3 or 4 hours- sometimes I only manage 1 hours sleep a night and its a nightmare trying to sleep and not being able to!
I normally exercise anywhere from 1pm to 7pm in the day (it varies) and don't go to bed till about 4am (insomnia) then need to get up about 9 or 10am but with only an hour or two sleep its so hard!

And added to this, last night I had chest pain- I felt as if I had just run a marathon: that burning sensation in my chest, slight breathlessness, I was not tierd, more over I felt as if I would have the energy to get up and do things had I not felt so emotionally tierd and had achey legs from cross trainer use.


Has anyone had any similar symptoms? I went to my GP who suggested an ECG which wont happen till next week when they and I am free to do this, she did a quick blood pressure test, said it all seemed normal but then it wasn't the 4am time when this was happening. Suggested a blood test for thyroid which I have not yet had, my last blood test in October was all fine so I can't see why it should have gone wrong all of a sudden.


I'm a little concerned as I'd like to carry on with what I was doing, it meant I could chop off about 20 mins of my workout as I had done everything in quick time and felt like I had really worked out, really empowering! But I don;t want to risk anything, I am 28, I am not sure if I should be having chest pains late at night/in the early hours of the morning. I always thought that as I worked out so much (5-6 days a week, 9-12 hours a week). I thought that if anything were to go wrong, my heart would be the last thing as I exercise it so much. But I am not so sure anymore- could I be causing damage or is this more likely to be a panic attack? has anyone else had similar symptoms from hard cardio exercise?
 
Don't let the bed bugs bite!

When I was reading through your post I thought...panic attack...then I got to the end of your post and saw that you have a similar conclusion.

There are a lot of reasons for sleeplessness, and exercise is more likely to help with a restful sleep than hinder it. It's good to get your heart checked out, so next week will tell you if you have high blood pressure or not. This concern could be your source of worry and finding out could kill two birds with one stone.

It's hard to say what you're so worried about that it's giving you anxiety, but I'd say, based on your description, that's exactly what it is. The symptoms are indeed distressing - I know this from personal experience. When we get ready for sleep we think about things, and if we have a worry, even if we don't know what that worry is, that's the time that it surfaces and gives us trouble sometimes in the form of insomnia or panic attack.

Until you get your heart tested, you should research some relaxation techniques and use those before bed, as well as employ all those things people do to get to sleep - a warm bath/shower, herbal tea, warm milk, meditation, soothing music...anything to calm your mind should do the trick. I can suggest music (with lyrics) because this distracts your thoughts and allows you to relax.

Another question begs, why are you training at such a high level? Are you a competitive athlete? The manual with your heart rate monitor should tell you that optimal fat burning occurs at 55-70%.

Good luck, and I hope you get to the bottom of the trouble soon.
