I'm a 28 year old female and for the past two weeks have been experiencing what I can only describe as a fluttering and heart palpitations every 30 minutes or so. I also notice that when at rest my heart rate goes down to around 50 bpm, this would be fine if it weren't for the fact it gives me an uncomfortable sensation in my chest when my heart rate goes that low. I do exercise 4 to 5 times a week but am in no way athletic.
I went to the GP yesterday about these feelings in my chest and he discovered I have a heart murmur, this has never been picked up so must be new. I am now booked in for bloods and an ECG tomorrow and referred for a heart scan.
I am incredibly worried as I have noticed for a few years that when my heart rate drops low I feel very uncomfortable and it drops especially when I am laying on my left side and I just never gave it much thought but now I'm worried that the sensations I've been feeling as well as the heart murmur may be something serious.
I just can't relax, am I be unreasonable for worrying so much about this?
