A Comprehensive Guide to Cardiac Implantable Devices: Pacemakers and Defibrillators Explained
Cardiac implantable devices, including pacemakers and defibrillators, have revolutionized the management of heart rhythm disorders. These devices, which are surgically implanted to help regulate the heart's electrical system, play a crucial role in saving lives and improving the quality of life for millions of people worldwide. Although both pacemakers and defibrillators are used to address heart rhythm issues , they serve different functions and are tailored to treat specific heart conditions. This article examines the distinctions between pacemakers and defibrillators, their applications, and the technological advancements that continually enhance patient outcomes. Pacemakers: Restoring Normal Heart Rhythms A pacemaker is a small, battery-powered device that is implanted under the skin, typically near the collarbone. Its primary function is to help regulate slow heart rhythms, a condition known as bradycardia. When the heart’s natural pacemaker (the sinoatrial node) fails to gene...
