Návrh zařízení pro měření variability srdeční frekvence

Abstract

Heart Rate Variability (HRV) is the variability of time intervals between successive heartbeats. The thesis focuses on designing a device to measure HRV using an ESP32 microcontroller. The device will measure HRV from the photoplethysmographic pulse wave using the MAX30102 sensor. Furthermore, the work addresses the programming and implementation of an algorithm to evaluate heart rate variability from the collected data, which will be stored on a memory unit and an MQTT server. Signal reconstruction in the MATLAB environment will be used to verify the reliability of the implemented algorithm for detecting systolic peaks. Measurements will be performed on at least 15 participants aged over 18. HRV will be analyzed in the time domain, and the effect of regular physical activity on HRV will be examined.
