Cardiac performance monitoring system for use with mobile communications devices

This describes a way for a smartphone to monitor heart health by using its built-in accelerometer to record tiny vibrations on a person's chest caused by their heartbeat. These vibrations create a seismocardiogram (SCG), which the phone then analyzes to identify specific heart events and assess cardiac function. It can also incorporate an electrocardiogram (ECG) for more data.

Why it matters: Smartphone accelerometers and processing power have advanced significantly since 2013, making on-device SCG analysis more accurate and reliable. Modern AI and machine learning techniques can now more effectively identify the subtle characteristic regions of the SCG.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
