Everything went well yesterday. Sent me home about an hour after the procedure.
Back this afternoon to have the pacemaker checked. Firing on both cylinders.
Inconvenient to have my left arm strapped to my side, but need to let everything start healing.
The rest of potential heart problems don't seem likely. No stents, bypasses, etc. Arteries and veins don't have plague, and my heart itself seems strong. All in all, reassuring.
