The present invention relates to the field of blood pressure measurement, and particularly relates to a method and a device for measuring blood pressure. The method includes the steps of: acquiring an electrocardiogram (EGC) signal acquired by the acquisition unit processing the acquired EGC signal extracting feature information from the processed EGC signal and calculating blood pressure according to the extracted feature information. The present invention is able to extract feature information from the EGC signal and calculate blood pressure according to the extracted feature information, thus avoiding discomfort from a cuff sphygmomanometer and inconvenience from an invasive sphygmomanometer.本發明涉及血壓測量領域,尤其涉及一種血壓測量方法及裝置。該方法包括步驟:獲取一心電採集單元採集的心電圖信號;對所述獲取的心電圖信號進行處理;從所述處理後的心電圖信號中提取特徵資訊;及根據提取的所述特徵資訊計算出血壓。本發明中的血壓測量方法及裝置能夠從處理後的心電圖信號中提取特徵資訊,並根據提取的所述特徵資訊計算出血壓,避免了現有袖帶式血壓計使用時造成用戶不適及侵入式血壓計使用不便的問題。S401~S404‧‧‧步驟
