A kind of health index monitoring alarming device, to solve the problems, such as that known list judges whether that heart disease is easy to cause erroneous judgement with rhythm of the heart information. System includes: a shell, has the several apertures for being connected to an internal room One expands mould group, and there is neighbour to set several transmission interfaces of what several apertures One rhythm of the heart measurement unit couples the expansion mould group with a Port One processing mould group, if the what room and being electrically connected the expansion mould group and the mould group of warning, the processing mould group controls the rhythm of the heart measurement unit and measures one rhythm of the heart information of acquirement, and whether analyze the rhythm of the heart information normal, if analysis result be it is no, control one is warned one alarm notification of sending of mould group, the expansion mould group is set separately to link an auxiliary measurement unit, and unit measuring is measured with the auxiliary and obtains a physiology information, and re-starts parsing according to the rhythm of the heart information and the physiology information, to update the rhythm of the heart information.一種健康指數監測警示裝置,用以解決習知單以心律資訊判斷是否心臟疾病容易導致誤判的問題。係包含:一殼體,具有連通內部一容室的數個開孔;一擴充模組,具有鄰設於該數個開孔的數個傳輸介面;一心律量測單元,以一連接埠耦接該擴充模組;一處理模組,設於該容室且電性連接該擴充模組及該示警模組,該處理模組控制該心律量測單元量測取得一心律資訊,並分析該心律資訊是否正常,若分析結果為否,則控制一示警模組發出一告警通知,使該擴充模組另連結一輔助量測單元,並以該輔助量測單元量測取得一生理資訊,並依據該心律資訊及該生理資訊重新進行解析,以更新該心律資訊。1‧‧‧殼體11‧‧‧容室12‧‧‧開孔2‧‧‧擴充模組21‧‧‧傳輸介面3‧‧‧心律量測單元31‧‧‧連接埠4‧‧‧示警模組5‧‧‧處理模組6‧‧‧電池單元7‧‧‧綁固件8‧‧‧人機介面9‧‧‧按鍵組件91‧‧‧電源鍵92‧‧‧功能鍵93‧‧‧重置鍵
