Storyboard Text

  • Paul Maurice Zoll was born on July 15, 1911 and died on January 5, 1999. He was a Jewish American cardiologist and one of the pioneers in the development of the artificial cardiac pacemaker and the cardiac defibrillator.
  • In 1950, a presentation in a congress of the American College of Surgeons, about the stimulation of the sinoatrial node through a transvenous catheter, inspired Dr. Zoll to develop a technique to stimulate the heart rhythm during asystole without opening the thorax. In 1952 he described the cardiac resuscitation by using electrodes on the bare thorax with impulses of 2 milliseconds in duration, of 100 or 150 volts, at a rate of 60 stimuli per minute.
  • But his model did not work correctly ...
  • : (
  • Then ... Wilson Greatbatch arrived (he was born on September 6, 1919, Buffalo, United States and died on September 27, 2011, Williamsville - New York), he was a great engineer and inventor.
  • American engineer Wilson Greatbatch was working with a type of machine that recorded irregular heartbeats when an incorrect type of resistance was inserted into his invention. The circuit pulsed and then stopped and then again pulsed what prompted Greatbatch to compare this reaction with the human heart and worked on the first implantable cardiac pacemaker.
  • Currently, the pacemaker is very important because it perceives when the heart is beating irregularly or very slowly. It sends a signal to the heart, which makes it beat at the correct pace, causing heart attacks or cardiac arrests to be prevented, thus preventing the death of many people.
