Heartfelt Technologies has developed a device with an optical sensor to monitor heart patients automatically in the comfort of their home. The Heartfelt device can be easily installed in the patient's home and will track the foot volume of the patient over time whenever the patient simply walks past the monitor. As leg œdema is one of the main symptoms associated with heart failure decompensation, it is one of the signs to keep an eye on. The data is then transmitted to ‘the cloud’ for further processing and flagging of high-risk patients. Once flagged, our data can feed into existing telemedicine monitoring systems allowing carers and medical professionals to take prompt action.
