Wow, what a week.
On Monday afternoon, I went to the GP to get my prescriptions renewed. She took my blood pressure, listened to my heart, and asked me whether I had private health insurance. I said 'yes' and she called an ambulance to get me to hospital. Apparently I was experiencing atrial fibrillation and my heart rate was 170 beats per minute. I was feeling fine so it took me completely by surprise.
Nathan met me at Emergency. I received a shot of blood thinners, and some meds to stabilise the heart rate and was then wheeled into a room where I spent the following two days getting a bunch of tests done.
I'm now on some new meds and have to go back to see the cardiologist in a few weeks. On the plus side, things I had associated with getting older (e.g. feeling dizzy when I stood up) was probably due to my condition so at least I can now receive treatment for it.
