 Impedance cardiography

Impedance cardiography (ICG) is a non-invasive diagnostic technique used to assess cardiac function and hemodynamics by measuring changes in electrical impedance in the thorax. The principle behind ICG is based on the fact that blood has a different electrical conductivity than surrounding tissues. ### Key Features and Process: 1. **Measurement Technique**: Electrodes are placed on the skin, typically around the neck and chest.
