Of course, I've learned all this in a week, so I'm a little fuzzy on the details--I been reading blogs and product literature and listening to podcasts. It's like trying to learn Mandarin and then having a conversation. It's brand new even to the experts, IMO.
In September I was told I was not a candidate for a pacemaker (originally developed in the late 50s) and here I be, now ready for the moon! If you have one of these in your heart, let me know--I've yet to meet anyone who does. And if you're a direct descendant of Grandma Bessie, we might want to talk.

"How does it work?
In the dual chamber system, two small devices are implanted, one in the atria, one in the ventricle. Communicating by sending signals through the blood, these devices help the heart beat more naturally. Called atrioventricular (AV) synchrony, this coordinated contraction of the heart – first atria, then ventricles – is the most efficient way for the heart to pump blood. More importantly, it helps patients feel better sooner than earlier pacemakers.
The minimally invasive procedure to implant the device takes about 45 minutes – averaging 20 minutes per chamber. Patients receive sedation and a local anesthetic. The surgeon makes a tiny incision in the groin and threads a small tube, or catheter, through the blood vessels into the heart, guided by real-time X-ray images.
The cardiologist inserts the two individual pacemaker capsules through the catheter and attaches them to the wall of the right atrium and the right ventricle. After the catheter is removed and the incision is closed, most patients spend an hour or two in the hospital before going home." https://utswmed.org/medblog/leadless-pacemaker-benefits/
