CardioSense – easy to wear ECG monitor for use over longer periods

The focus of the CardioSense project is to make cardiac rehabilitation (rehab) more efficient by moving rehab to the home. CardioSense allows patients to train themselves in the comfort of their own home and at the same time give them the reassurance that when something goes wrong the sensor picks it up and sends help. Within the project 2M develops a ecg monitor for daily use. This device should be easy and comfortable to wear over longer periods. Measured data must be medical grade accurate and reliable. Smart algorithms perform a real-time analysis to observe and/or alarm in case of a deviation or emergency. This information is send to the cloud, where it can be accessed by care professionals. This information can also form the basis for automated and adaptive coachingsprograms.

The wearable ECG sensor / recorder

The wearable ECG sensor is a device that can be used over longer periods in the comfort of the home, without causing any skin irritation over time. The user should be able to use it without hassle themselves, without outside help. The device is strapped on or integrated in existing clothing.

Key features

  • Quality ECG recorder for home use. Use over longer periods.
  • High-resolution (1 lead @ 256sps at 23bit resolution) storage on SD-card for research purposes.
  • On-board signal processing for specific heart problems.
  • Bluetooth Smart connectivity for sending essential (compressed) information to smartphone / cloud.
  • Measures: ECG (HR & HRV), activity / movement, temperature
  • On device real-time alarm feedback

Smart Signal Processing – Atrial fibrillation

Within the wearable sensor device the ECG signal is analyzed in real-time using smart signal processing for specific heart related problems. After consultation with a leading cardiologist in the Netherlands 2M decided to first focus on reliable and real-time detection of atrial fibrillation. Based on existing publications, literature and our own thinking we have come up with improved algorithms that reliably work on all existing MIT databases. These algorithms are also available on the embedded platform. Next step is to validate these algorithms.

Depending on customer interest 2M can create algoritms for other heart related problems.

Current status

At the moment 2M finalizes the product design, hardware and firmware development for the first prototype. After internal technical testing, we will collaborate with academic partners for further validations. This is project is done in cooperation with Lode. Lode creates the cloud environment and the online training tool.
