We spent the afternoon yesterday in the Cath Lab at the hospital in Prescott.
That's the Cardiac Catheterization Lab to those of you not in the know.
It's where doctors perform minimally invasive tests and advanced cardiac procedures to diagnose and treat cardiovascular disease.
So explains the Google.
What it meant to us is that Judy had to have her pacemaker replaced.
The one she'd been living with for 9 years had finally lost enough battery strength to require a new one.
Here's what a pacemaker, or generator, installation looks like.
It is typically placed just under the skin with wires, or leads, running into the chambers of the heart.
In Judy's case, the leads were doing just fine so the new device was just hooked up to them.
The purpose of the "machine" is to maintain an even heart rate when something has caused the natural rhythm to falter.
Judy went in for her surgery at 4:15 and came out about an hour and a half later, feeling fine but looking a bit woozy from the anesthetic.
