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

Advanced cardiac devices, including pacemakers, play a vital role in preventing sudden cardiac arrest and supporting heart function in patients with heart failure. These devices help coordinate heart chambers, detect dangerous heart rhythms, and deliver life-saving therapy when needed. As explained by Dr. Vanita Arora, Senior Consultant & Clinical Lead - Cardiac Electrophysiologist, an early evaluation by a cardiac electrophysiology specialist can help identify whether a pacemaker or other advan
