Appreciate all the replies.
Ginger, I am not a pilot - I used to run the other side of the cockpit door - get what you mean but again just describing how I felt and what I felt.
LR = yeah you're right, if something happens that hasn't before it is very scary indeed.
Jim - if you do a search myself and several others had a thread going about the heartbeat issue. Beta blockers are weird things - had no issues previously but these are making me feel quite odd, so much so I am going to speak with the doc to ask for an alternative - they have never stopped my irregular beats but, as I mention previously, they have gone the whole hog with me and found nothing wrong "top part of the engine is sensitive"
Step by step I guess and we'll see.
Thanks
HR
