Thanks for the thoughts johnpitcairn and dalai.

@ kieranl; WTF moments, like sh#t, happen. I guess we are all, including doctors, on a learning curve while we weave the tapestry of life with our individual threads.

@ lightfoot; Thanks for the offer of giving a hand, though I/we have most things pretty well covered for the time being, and with every passing day I am able to do more, so all is good. I will eventually catch up with you for a cuppa though!

@ ImaSYL; I laughed out aloud at your post and reflected that it is good to still be here in order to do that!
Who knows, you could be right? ... and I will put my experience down to the sins of my youth!

Last page I wrote;
>I'm about to go for my long awaited first push bike ride in 4 months, on easy ground, to see how that goes...

I rode for an hour (11 km) on the easy ground of mostly tar, with a short section of fire trail thrown in for good measure of how vibrations and bumps of uneven terrain affects me; and I'm pleased to report that all is good, though it showed me that they forgot to put my endurance back in when they closed me up again after the retrofit.
To be sure, to be sure, I again rode for an hour and a quarter (another 11 km) the following day on mostly flat-ish fire trails with a little bit of easy single track thrown in to measure how that would go. Once again it went well, though that time frame pulls me up at the moment; as after it I feel like I used to when I finished two and a half hours of solid workout type riding when I left off last October.
~> I guess I will have to ride around the bush some more to try and find the elusive endurance thing... heh, heh, heh; though I'm still not up for anything single track other than the easiest of it.

A further observation on performance and a retrofit allegedly being kind of like being supercharged, re cardio-pulmonary efficiency generally.

At about week six I queried the Cardiologist as to an event where my breathing seemed out of sync with the activity I was doing.
I was bush walking on a track and just surmounted a short rise that was stair-like in nature and the equivalent of going up two floors in a building. Although I didn't feel puffed, my breathing was at a rate commensurate with having just finished a 200 m sprint!
She told me that was due to the Metoprolol drug she had prescribed me, and I could now stop taking it as it was obvious to her from that experience that it was now holding up my recovery progression.

Metoprolol is a drug that slows the heartbeat rate. If one is taking it and 'exercises' to a point where the body demands more oxygen, because the heart can't beat faster to get blood oxygenated through the lungs quicker, then the lungs try to make up the deficiency by going overtime to meet the demand.

It's a potent little pill only 3mm in size and I was on half dosage rate so having to cut the pills in half. She told me not to stop taking it cold-turkey, but to cut the pill into quarters and take a quarter daily for three days to wean off it.
After I got off it, my performance was enhanced magically like having a light switched on, ... though so far that is the only supercharging experience I have had in the process to date.

Other folk may experience different performance aspects with heart conditions, especially heart electrical related issues.
