Abstract
A system and method for cardiovascular monitoring and reporting are disclosed. The system (CV monitoring system) includes a data analysis system and an in-ear biosensor system that preferably includes left and right earbuds. The earbuds include infrasound/vibration sensors that detect biosignals from the individual including signals associated with cardiovascular activity (CV signals). The analysis system calculates cardiovascular function measurements (CV function measurements) based upon the CV signals. The CV monitoring system uses machine learning to predict blood pressure (BP) measurements of the individual based upon the CV signals and the calculated CV function measurements. In an embodiment, the CV monitoring system includes an EKG detection system that detects EKG signals associated with heart function. The analysis system can calculate additional CV function measurements from the EKG signals to augment the CV function measurements calculated from the CV signals, and predict BP measurements using the full complement of CV function measurements.
