A pacemaker is a device implanted during surgery, which delivers electrical impulses to the heart to stimulate its rate from going too slow, which is often referred to as bradycardia. #HeartHealth #HeartMonth #pacemaker | Marshfield Clinic Health System

⚡️ 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
