The computerized cardiac analysis system, which acquires and analyzes the electrical
activation signal propagating along the surface of the heart, is indispensible equipment
for the open heart surgery and electrical cardiac functional study. The 128 channel cardiac activation amplifier under the electrosurgical unit is disordered because of DC offset and saturation in differencial amplifier. In this paper, the base-line compensation circuit for removing DC offset in cardiac-activation system is designed.
