The Evolution and Impact of Pacemakers: Revolutionizing Cardiology

The video discusses the evolution of pacemakers, from early external devices to modern implantable ones. It highlights key developments, such as the accidental discovery by Wilson Greatbach in 1958, which led to the first implantable pacemaker. Technological advancements have made pacemakers smaller, more reliable, and capable of real-time heart rhythm adjustments. The video also covers the significant impact of pacemakers on reducing cardiac arrest risks and improving patients' quality of life, while acknowledging potential risks. Future advancements are expected to make pacemakers more affordable and sophisticated.
