First Pacemaker

The guy who got the very first heart pacemaker implant in 1958, Arnie H.W. Larson, lived for 43 more years, until age 86 in 2001. That first one wasn’t his only pacemaker. It was replaced with 25 others, keeping him in good health until his last year. Nowadays, pacemakers are easily implanted with local anesthetic, but when he got his, it was about as traumatic as the first heart transplant was in 1969.
