Hi all. 2 weeks ago, I had an ecg, which detected ectopic beats, which was the main reason I had one done, but it also questioned whether I’d had a recent cardiac event. I’ve had chest pain along with the palpitations, but nothing like I’d imagine a heart attack would feel like! 😐 Anyway an urgent 24hr ecg and echocardiogram were requested by my GP. The 24hr ecg I had done last week, and the echo this week. I had a cardiology appointment booked for 15th Dec to discuss results. However, I got a call on the afternoon of my echo, from my GP, asking me to go to the surgery straight away. When I got there, the GP said that my 24hr ecg showed abnormal beats and that I was to be seen urgently, the same day (although this was 4 days later!) The GP needed to check me over and ask how bad my chest pains were. I said they felt like a heavy crushing type pain, more of an ache really, so was told that was ok, but they needed me to see the cardiologist sooner. I got a call straight away for an appointment in a weeks time. Since then I purchased an oximeter. Tonight, and last night and throughout today, my pulse will be around 100-107, then suddenly drop down to 28. When this happens I feel faint, and my heart is pounding (I’d been getting those symptoms, but didn’t know why before the tests and oximeter. Anyway, I know I see the cardiologist now in just a few days, but am worried sick. Why could this be happening? Is it dangerous to be dropping that low? I’m a 45 year old female, and had always been very fit, up until 2 years ago, when I got arthritis in my spine, knees and ankles, and recently I’ve discovered I have high thyroglobulin antibodies, which I was told is Hashimoto’s. My other thyroid levels are middle normal range.
