When these signals go awry, major health issues such as heart attacks can occur. Enter the pacemaker, a small implanted device that keeps your heart beating. But did you know, implantable pacemakers were invented by accident? This title explores the history, struggles, and the accidental invention of the pacemaker, a device that beats hundreds of thousands of times each year to save people's lives."-- ER -
