Mfine launches heart rate monitoring tool on its app

Bangalore, March 6

Beyond telemedicine consultations and health services, digital health startup MFine has launched a Heart rate (HR) monitoring tool on its app which allows users to track their heart rate without the need of any additional device or any other app.

Currently, 700 people are said to use the tool to monitor their heart rate every day on MFine. The company is working on various next-generation artificial intelligence technologies that transform the mobile phone into a rich diagnostic and vital signs monitoring tool. Mfine also plans to launch glucose monitoring and blood pressure measurement via its app by the end of 2022.

Ajit Narayanan, CTO, MFine said, “Globally, we are seeing a massive transformation in how people manage their health with an increased focus on preventative health and home screening for chronic disease monitoring. . The combination of medical diagnostics with smartphones will greatly advance the assessment, diagnosis and treatment of critical health conditions. By enabling vital signs monitoring via smartphones, MFine is making assessments universal and free for millions of people in India who otherwise would have found it difficult to do. With artificial intelligence, global health data can play an incredible role in disease estimation and early diagnosis. At MFine, we are excited to lead this major transformation and contribute to the use of smartphones as a diagnostic tool.

Proprietary algorithm

The health tech startup has built a proprietary algorithm that measures heart rate using the smartphone camera. Heart rate is measured by the photoplethysmogram (PPG) signal from the user’s fingertip which is obtained by detecting changes in blood volume below the surface of the skin. The PPG is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissues. Each time the heart beats, the amount of blood reaching the finger capillaries swells and then decreases. Because blood absorbs light, the MFine app is able to capture this ebb and flow using the phone’s camera flash.

The LED illuminates the skin and the smartphone camera measures changes in light absorption. The signal is then broken down into red, blue and green parts and using the difference in levels of light absorbed on these different wavelengths, the heart rate is calculated by a machine learning algorithm. Variations in light intensity are related to changes in blood perfusion of the tissue and, based on these changes, information relating to the heart can be retrieved.

Currently, the heart rate measurement tool has 90% medical grade accuracy. The tool is in public beta for Android users and will soon be launched for iOS users. MFine is preparing for certification of its algorithms, with data from hundreds of measurements to give medical-grade accuracy and reliability to the algorithm.

In 2021, Mfine launched an SPO2 monitoring tool on its app which has been used by over 600,000 users. The tool allows users to track their oxygen saturation levels without the need for an additional device.
