A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .
As a boy, Bakken was inspired by the combination of electricity with medicine in Mary Shelley's novel Frankenstein, and the subsequent 1931 film version starring Boris Karloff was a direct inspiration for his future work, including his improvements to the pacemaker (the first to be battery-powered and wearable) and founding Medtronic.
