hi
I am a 16 year old female with current Anxiety disorders.
I had an ECG about a couple of months ago because of heart complaints,
it came back with Sinus arrhythmia, which is normal.
But yesterday when I was lying down on the sofa i felt this constant fast one beat thumping in my chest and then i had it againand then it went back to normal again, I often get it when i am stretching, but ever since then i can feel it more in my chest. Often, esepically at night or when i am hungry i can feel it more and it starts to "jump"
What exactly is Sinus arrhythmia and can putting your chest under "strain" make the symptoms worse?
anybody have the same problem?
