Okay, so it used to happen every now and then, but its getting more and more frequent.
Today I have had it happen three times already.

Ill be doing what im doing, whether its sitting down watching tv, or washing the car, and all of a sudden, my heart starts racing heaps quickly....like i can literally feel it beating VERY fast....and ill start having probllems breathing or getting a breath of air in.

It generally only happenns for about 30 secs-minute each time, as long as i relax and start really concentrating on getting a breath in.

Its very scary, and my DP thought it may have just been anxiety. But im not worried or anxious about anything, so im pretty sure its not anxiety.

Please help, what could this be??
I have booked into the docs for this arvo, but im just scared she will brush it off, and not really realise how scary it is.

just after some advice
