Electrocardiogram (ECG)

ECG equipment requires the precise extraction of microvolt-level bioelectrical signals from complex physiological backgrounds. To address the high susceptibility of electrode interfaces to electrostatic discharge (ESD) from the human body and the severe impacts of high-frequency electrosurgical units and defibrillation pulses in the surgical environment, we offer a protection solution with high surge resistance and ultra-low parasitic capacitance. These high-performance components, while ensuring accurate and distortion-free ECG waveform reproduction, construct a robust physical barrier for the sensitive amplification and sampling circuitry at the back end, guaranteeing the continuity of medical diagnosis and patient safety.
