There was a time when whether or not I would continue to have a pulse was a matter of considerable discussion. Apparently, if I didn’t have a lot of surgery, it was going to go away and not come back.
I didn’t like that idea much, so eventually, I had the surgery. Two pig valves, one myocardial-something-or-other-y in the left ventricle, a bypass, and a Pacemaker later, everything pulses in a reasonably tidy, efficient way. As long as the batteries don’t wear out, or one of the animal valves stops working, I’m good to go.
So far, anyhow.
