Good news was, it wasn’t.
I was unwell last week and my heart felt a bit jittery, then I cracked a tooth on the weekend and had horrific pain. Last night (Sunday) my heart went crazy. It felt a lot like fast AF - up to 140bpm - for about 2 hours. I took a few Kardia readings which kept saying “possible atrial fibrillation” which I sent through to my EP today who said - no AF - it was sinus tachycardia with lots of ectopics. So, whilst I was uncomfortable last night, I was pleased to hear this news.
And as for the tooth, I got into my dentist today for an emergency appointment and needed a root canal and crown - not so good news.
