Swampscott doc donates antique pacemakers Salem Hospital

North Shore Medical Center to dislay Linda Werbner Sign up for the Swampscott Reporter’s newsletter. “Ginormous” is the word cardiologist Dr. Lawrence Block used to describe the bulky, near-hockey puck sized pacemakers of the early 1960s that came with batteries. Compared to today’s tiny pill-size devices, his description says a lot about the speed of technology. “Over the last three decades there have been tremendous improvements,” said Block. “They’ve gotten smaller and smaller and smarter and smarter.” These life-saving devices stabilize heart rhythms by applying electrical impulses to the heart.  Initially, the pacemaker had a single wire which went through a vein into the right ventricle,” he said. “By 1990, two-wire systems were developed enabling coordination of the upper and lower chambers and improving the heart’s pumping function. And today the batteries last up to 10 years or more.”
