⚡️ Pacemakers 101 A pacemaker is a small, battery-powered device that helps regulate abnormal heart rhythms. Implanted under the skin, it monitors the heart’s electrical activity and delivers impulses only when needed to restore a healthy beat. The system has two key parts: Pulse generator: battery circuit creating impulses Leads: thin wires carrying signals to the heart muscle Modern pacemakers are often “on-demand,” supporting the heart only when it needs it. #Cardiology #Pacemaker #Arrhythmia

Scientists have developed an ultra-small, fully dissolvable pacemaker designed to temporarily support the heart during recovery. Unlike traditional pacemakers that require surgical removal, this device naturally breaks down inside the body after completing its job—representing a major leap toward safer, less invasive cardiac care. • The device is roughly the size of a grain of rice and made from bioresorbable materials • Designed to provide temporary electrical stimulation during early healing •
