Abstract
The present invention relates to an AI-enhanced wearable photo-electro-tonoarteriography (PETAG) method and apparatus. The invention relates to the technical fields of medical detection and artificial intelligence, and is applicable to, such as, tonoarteriogram (TAG) signal estimation, which is continuous blood pressure and cardiac diseases detection. The method comprises: acquiring at least one lead electrocardiogram (ECG) signal and multi-wavelength photoplethysmogram signals (MWPPG signals); processing the ECG signal and the MWPPG signals by a multimodal model-based multi-task learning network, determining a signal processing result related to a TAG information and/or related to a cardiac disease information. The present invention is advantageous in reducing computational cost involved in signal processing on the basis of ensuring accuracy.
