Abstract

Background: Pulse wave, as a carrier of human hemodynamic parameters, can reflect the hemodynamic state of the menstrual cycle. Objective: To explore the influence of pulse wave shape and pulse rate variation on menstrual cycle and dysmenorrhea. Methods: The pulse waveform data of 20 women during the whole menstrual cycle were collected and monitored, and the waveform characteristics and pulse rate variation characteristics were calculated. Results: The characteristic parameters of waveform and pulse rate variation increased first and then decreased with the development of the menstrual cycle. Characteristics were associated with dysmenorrhea at different stages of the menstrual cycle. Conclusions: The findings of this study highlight the physiological significance of pulse wave characteristics and heart rate variability parameters in relation to the menstrual cycle and dysmenorrhea. These results provide new insights into the physiological mechanisms underlying pulse wave changes during the menstrual cycle and offer potential guidance for the diagnosis and treatment of dysmenorrhea.
