Cardiac mapping is a technique used in the field of cardiology to create detailed visual representations of the electrical activity of the heart. It involves using specialized equipment to measure and record the electrical signals generated by the heart, which can help diagnose and treat various heart conditions such as arrhythmias and heart failure. Cardiac mapping can provide valuable information about the overall health and functioning of the heart, as well as help guide treatment decisions for patients with cardiac rhythm disorders. This technology has revolutionized the field of cardiology and has greatly improved the outcomes for patients with heart conditions.
