The worn smart devices are becoming more popular every year as a fashion product, bringing people closer to technology. As competition in this market grows, the functionality of these devices is increasing at the same time. Users no longer only need to track physical activity and heart rate. Today’s technology makes it possible to install sophisticated data processing algorithms into the smart devices, and the latest sensors provide the ability to record increasingly high-quality physiological signals. The popularity of smart devices and technological advancements greatly simplified the monitoring of physical condition and general health that does not restrict peoples’ freedom.
The is a method for monitoring cardiac efficiency without restricting the freedom of the user’s movements, based on automated measurement of the time of recovery of rhythm after physical activity. Clinical studies have proven the heart rate recovery abilities for the cardiac performance evaluation. So far, this cardiac performance evaluation method has been used only in controlled trials due to complications related to movement noises and complex signal processing. The new method simplifies signal-processing, separates heart rate recovery segments more effectively, making the integration into portable devices easier. The popular smart wristbands are perfect for monitoring recovery without completely limiting your normal activity. Even the simplest daily physical activity, such as climbing stairs or walking, requires a lot of energy and causes a certain amount of stress to the heart, increases heart rate.
The photoplethysmogram sensor, integrated into the smart wristband, delivers a high-quality pulse signal. The signal is processed in real time and separates the human pulse rate. During the day, physical activity episodes are detected, followed by a consistent, undistorted recovery of the heart rate. The main parameters of the recovery curve are calculated, measuring the 3-minute pulse sequence variation in various recovery phases. The parameters are combined into a separate index that evaluates the cardiac efficiency and the ability to recover from the stress caused by physical activity. Total cardiac performance is estimated throughout the day-week period. A person can monitor the variation of this estimate over time, thus assessing changes in his physical condition. The method can be useful to both regular users of the wristbands and to the evaluation of the effectiveness of rehab programs in the treatment of heart disease.
