How a Pacemaker Works: Heart Anatomy and Device Integration Explained #3531409 (License: Personal Use)

This medical illustration depicts a dual-chamber pacemaker implanted near the heart, with pacing leads threaded through the superior vena cava into the right atrium and right ventricle. The pulse generator houses the battery and circuitry that monitors and delivers electrical impulses to maintain proper cardiac rhythm. Labels identify major cardiac structures-including left atrium and left ventricle-to contextualize device placement and function.

Used in cardiology educational content, patient brochures, or telehealth platforms to explain pacemaker implantation and function; targets patients diagnosed with bradycardia or heart block seeking to understand treatment options.
