G'day CD,
Funny you should post that ...... had a weird time last night (about 3.45am and sleeping on my left side) and came to a similar conclusion. Woke up to several squadrons of butterflies having a dog fight on left side of chest. HR was 64 bpm, an ECG trace on my handheld device showed erratic ( as opposed to chaotic) behaviour with the comment 'signs of irregular beat activity'.
The dogfight went on for about 90 minutes and everything settled down - the good guys won My bet is a short sharp mugging of Atrial Flutter. And I hadn't been acting like a mountain goat either
So then started the analysis of why ? In the morning I'd been to my local Chiropractor for a 20 minute maintenance session for my mischievous back. In the evening about 6.30 had an M & S Chinese meal .... the one you buy and then take home and heat up (or whatever the process is). The Chinese was a little spicier than I would like but no issues at the time or shortly after. I'll put it all down to vagal nerve again, stirred up by a combination of Chiropractic work and ingredients of the Chinese, and sleeping on left side ! As I write, I'm as fit as if I'd played a 50 over cricket match in the middle of a Sydney summer.
On the photographic side of things the attached illustrates my walking abilities ..... a shot of part of the Hayle Estuary .... no I don't do hills like in the back ground, just the foreshores of the estuary, that's my limit. Its flat

NB: Just found the packaging of some of the Chinese .... soyabeans, different ingredients of roast pork incl. crumbed roast pork crackling and a wide range of spices ..... well that'll do it every time ! "Stupid boy" as Capt Mainwaring would say. And of course the time from when the meal finished to when I woke up would correspond to the time the food would go through the digestive system.
