Pacemaker - a dead ringer for the human heart - the Awesome World of Things

Wilson Greatbatch, an assistant professor at the University of Buffalo thought he had ruined his project. Instead of picking a 10,000-ohm resistor out of a box to use on a heart-recording prototype, Greatbatch took the 1-megaohm variety. The resulting circuit produced a signal that sounded for 1.8 milliseconds, and then paused for a second—a dead ringer for the human heart.
