Putting diagnostic technology in your hands.

At ElectronRx we understand the desire of individuals to monitor their cardiovascular health, as easily as possible. Using a smartphone app and onboard camera to collect fingertip PPG data, we provide the user with a window into their cardiovascular health. Our aim is to provide a low cost, medical-grade cardiovascular health monitoring platform for patients, at-risk groups and the worried-well.

No external devices - assess your cardiovascular health using only your smartphone.

A low-cost convenient solution to personal blood pressure, cardiovascular health monitoring.

Patient data will be stored anonymously and shared with their clinician with the user's consent.

How you can benefit?

Monitoring your cardiovascular health at home can help you make an earlier diagnosis of atrial fibrillation, identify pre-hypertension and vascular stiffening, giving you feedback about your health and helping you to feel more in control of your condition. Home monitoring can also give your doctor or nurse a more complete picture of your day-to-day cardiovascular health.


How it works?



Using the smartphone camera we record the PPG signal at the fingertip, which corresponds to the fluctuations in the perfusion of the blood vessels in the finger with blood as the heartbeats and the pulse propagates through the body.



Based on the number of peaks per minute, the shape of the PPG waveform and a machine learning model correlating the PPG waveform to blood pressure, we provide a series of metrics describing the user’s cardiovascular health. These include heart rate variability, vascular elasticity, and blood pressure.



By recording a series of point measurements over the course of weeks and months we can see trends in these metrics, giving the user and their clinician useful information about their cardiovascular health.


What is PPG?

It is a well-established technology based on optical feedback, that has been integrated into many wearables. PPG (photoplethysmography) is a non-invasive optical signal, which gives information about the volume of blood flowing through the body testing zone, close to the skin, convenient for real-time measurement. During PPG data collection, light is beamed onto the skin in the recording area- as your blood perfuses into your skin, you see brightness changes in the light coming back from the tissue which corresponds to your pulse.
