Have a wonderful holiday booked for early next week. Kiddies and I abroad for a week, first holiday in two years. Yesterday I had a situation whereby my heart rate hit 170bpm whilst resting and refused to come down. My 16 year old called 999 and by the time I was admitted into hospital it had dropped To around 120. Chest x Ray clear, bloods clear, there was a blip on one ecg which dr said could be an AF so was admitted last night. Overnight it dropped to a normal resting rate but would rise dramatically as soon as I moved. Dr did not look at overnight monitoring and said for it to have been done properly a nurse would've needed to check on it regularly. Also advised yesterday it could have been a severe anxiety attack, I do get anxiety but never to this degree. Still feel absolutely pants. Basically been told they don't know what it is and would need an active ecg during the episode. Going to see GP in morning. So my dilemma is do I just go and risk this potentially happening mid flight again (nervous flyer) or try and plead with Tui/go through travel insurance? As dr at hospital told me though the issue is that they have no diagnosis for me. Either that or I face losing 6k that I've saved hard for. If anyone has any bright ideas I'd really appreciate them....
