Abstract:
1. A heart monitoring system for a patient, comprising: a Doppler radar formed with an IEEE 802 protocol transmitter and an IEEE 802 protocol receiver to detect heartbeat motion on a chest of the patient, wherein frequency waves are transmitted by the IEEE 802 protocol transmitter to the chest of the patient located a fixed distance from the transmitter, reflected frequency waves are received by the IEEE protocol 802 receiver from the chest of the patient, and the IEEE 802 protocol receiver is configured to generate a Doppler radar signal based on the reflected frequency waves; and an analyzer coupled to one of the transmitter and receiver including computer readable code configured to perform Doppler operations using the IEEE 802 protocol transmitter and receiver, wherein the analyzer calibrates a training Doppler radar signal with a training blood pressure during a training phase to develop a model and wherein the analyzer is configured to use the model with the Doppler radar signal during an operational phase to estimate blood pressure.
