Portable heart monitor
View Patent ↗A portable heart monitor includes a detecting unit to output a detecting light beam and receive a physiological response signal, wherein the physiological response signal is generated by the reaction of the detecting light beam and a finger of a user. The physiological response signal includes pulse waves of a perfusion index (PI). A processing and analyzing unit processes and analyzes the physiological response signal to acquire an analysis result, which is to be shown on a prompting unit. The analysis result includes heart status information based on processing of the pulse signals of the perfusion index (PI).
