The Phantom Medical Heart is a medical chair that measures a 6-channel electrocardiogram through four electrodes on both arms and legs. Integrating wireless communication technology, this product is designed to be able to link with medical device software (Software as a Medical Device, SaMD) which includes AI analysis technology. Using biosignal measurement, we have adopted the non-contact electrode. It generates a stable and high-quality ECG signal which conforms to international standards and through the AI analysis algorithm installed in the SaMD, this ECG signal can provide disease diagnosis and prognosis.
