Thank you .........
A sincere thank you to all of the respondants who have put my mind (and my heart) at rest. I was not at all concerned at all by any feelings of "ill health" within myself, in fact I feel that I'm fitter than others of my age. My concern was that I had failed, and continue to fail, to reach the nominally required Pulse Rate and BP even under stress, and by a large margin, even under prolonged stress.
The centre where I did my stress ECG mostly handles Air Force pilots in their twenties, the 180 bpm 'target' does seem to fit the various formulae offered by posters within this thread, and perhaps they have a fixation on this figure.
Younger PPRuNers, do heed Gingernut's advice about smoking. I fully endorse his remarks, it's only luck and good fortune in the genetic lottery that has enabled me to enter advancing age with minimal side effects!
Regards,
Old Smokey
