Whats wrong

I went to work on friday night feeling not well but not knowing exactly why. I knew my pulse was weirdly low and  I was feeling really tired and even walking down the corridor made me feel exhausted . I thought is my hemoglobin low, is my thyroid not functioning properly, am I getting asthma or old age, tiredness from playing golf for two days. I was taking vitamins and trying to do more fitness work. 

I got my mums sorted a bit and then did my blood pressure and pulse on the machine. My BP was ok as usual but my pulse was 45 I said to one of the girls do you think they would be worried about that in A&E. She said she thinks they'd admit you with that pulse. We decided that I should go to cas and get them to call me when they can see me. I went down and they triaged me and took me into one of the beds next minute they took blood put a cannula in, did an ECG and put me on a monitor. It was weird actually watching my pulse of 45 the nurse said stop watching it and turned the monitor away. There was a little parade of doctors I told my story to of vague symptoms a couple of colds breathlessness and feeling faint but not actually fainting. I think the first thing I noticed was getting breathless going up a small hill and having to stop to get my breath. They said they were going to admit me. I wanted to go and move my car but they wouldnt let me. I was trying to figure out what to do about the car. I cant remember what they said about the slow heart rate. It just felt really strange to be there but a relief too I was so tired of worrying about what was wrong now it was somebody elses worry so I just dozed on and off. I rang the girls on the ward to tell them what was happening and rang home. At 5am they moved me onto the cardiac step down ward and put me on a monitor. The girls came up from the ward and took my car home which was really nice of them.
