If you have complete AV block, a leadless pacemaker is less good than one with multiple leads, since it allows pacing multiple chambers and maintaining synchrony between A and V.
That's neat, although the left channel of my wireless earbuds drop out like 2% of the time!
What I want is a shoulder implanted pacemaker that's significantly smaller, with a quarter of the primary battery capacity, and an inductively charged supercap that can store enough charge to run at least week between charges.
