The Science Behind ECG

We believe the science behind what we do is the cornerstone of our business. That's why we've invested over 15 years in deep scientific research, securing the feasibility of ECG.

We work closely with leading cardiologists and sports scientists and have hired best-in-class researchers, engineers and software developers to advance ECG biometrics for a range of exciting commercial applications.

Here's how we're harnessing the power of ECG.

Understanding ECG

The ECG is a record of the bioelectrical activity during a heartbeat.

The bioelectric source arises during the heart’s electrical excitation process to produce a flow of electric current in the surrounding tissues, detectable with a pair of electrodes external to the heart.

The signal has several distinct features – the P wave, the QRS complex and the T wave – which make up the PQRST complex.

Variation in these signals provide a wealth of physiological information as well as providing a unique pattern per person.

Connecting Your Heart

These unique characteristics make the ECG an incredibly valuable signal to enable new and secure insights in wellness and health.

We're harnessing the power of ECG, to empower a range of features, ready to be integrated into products and services.

HeartKey® Signal Conditioning

HeartKey®’s intelligent and adaptive signal conditioning technology enables high accuracy ECG detention on dry electrodes in real time, forming the foundation of our more advanced algorithms.

ECG has been almost exclusively used in the medical industry due to its strength as a diagnostic tool, where the capture method can be highly controlled. Most ECG analysis software is designed for these ideal conditions and suffer in accuracy when adapted for commercial applications on dry electrodes.

 

HeartKey® Heart Rate

Heart rate is calculated through the precise localisation of the QRS complex and measuring the distance between each QRS complex (also referred to as R-R Intervals).

HeartKey®’s Heart Rate algorithm meets the medical ANSI EC57 standard, with regulatory certification in progress. The performance validation is available under NDA.

HeartKey® Heart Rate Variability (HRV)

HRV is a powerful tool for analysing cardiac and physical health and is a key input into many advanced algorithms including stress.

HeartKey’s® Heart Rate Variability algorithm complies with the medical ANSI EC13 and EC38 standard. The performance validation is available under NDA.

HeartKey® Physiological Stress

Your body exhibits several well known symptoms in response to stress, one of which is a change in the ECG.

HeartKey® continuously monitors your ECG and derives a quantitative measurement of your current stress state, enabling you to understand your body’s true state and
take appropriate actions.

 

 

HeartKey® Energy Expenditure

The HeartKey® algorithm takes in a user's physiological parameters and calculates the calories burned over a period of time. 

Energy Expenditure, also known as calorie burn, is an estimation of the amount of energy a person uses when carrying out various activities by measuring the cardiovascular function.

Understanding your expenditure and balancing it against your food intake is the most reliable way of maintaining a healthy lifestyle.

HeartKey® User ID

HeartKey®’s User ID uses your individual ECG to protect physiological data.This enables more refined customer analytics capability for the user, reducing the risk of data corruption. 

A human's ECG is varied due to a range of factors including the size and shape of the heart, the position within the chest and the conductive properties of the torso.
