Palpitations...again?

Like I said in Week 4's exercise log, I slept very badly this past Friday(25th Jan) night. I told the people I was to run with that I couldn't come and went back to bed. My domestic arrived a few hours later, and I went about a normal Saturday morning. I was plagued by an intermittent headache, but put it down to dehydration. I went for lunch with some friends and when I got home I took down some laundry off the line and was standing in my kitchen when I suddenly felt VERY faint. It felt like when you suddenly get up out of bed and all the blood drains from your head. I sat down quickly and started to feel palpitations. It feels a bit like someone is shaking your body, but no-one is touching you. I broke out in a cold sweat, went to lie on my bed. It took 2-3mins to pass.

What's really worrying about this is that I don't remember having a bout like this since when I was rediagnosed. However there are a number a of explanations. I could put it down to being dehydrated, or to a reaction to the local anaesthetic that was administered for a minor surgical procedure. I was prescribed an antibiotic (Levofloxacin) and a pain killer (Lentogesic). I specifically told the pharmacist that I had a heart condition and asked if these drugs were appropriate. She seemed to think so. I will find out if they have any side effects.

However, for those of you who may be concerned, I don't think you should be too alarmed. I went for a 6km walk this afternoon and felt fine, but I think to be on the safe side I will also make an appointment to see the cardiologist as soon as possible.
