Einthoven Goldberger Module for Physiology Lab

The Einthoven Goldberger ECG Amplifier Module is designed for capturing and amplifying ECG signals using Einthoven and Goldberger lead configurations for 6-lead ECG recording. It connects to four ECG electrodes and uses isolated input amplifiers to help avoid hum interference. The module provides bipolar Einthoven extremity leads I, II, and III as well as unipolar Goldberger extremity leads aVR, aVL, and aVF. The six ECG output signals can be connected to a system bus for recording or computer-based data acquisition. Manufactured by Atico Export with a focus on precision, durability and consistent performance for physiological research and experimental laboratory use.
