Abstract:
1. A handheld device for configured to detect electrical and mechanical cardio-vascular activities of a patient, comprising: a case; a plurality of ECG electrodes mounted to the case and configured to contact the patient; a transmitter mounted in the case and configured to transmit electromagnetic signals of a predefined frequency into the patient, a receiver mounted in the case and configured to receive reflected Doppler frequency shifted electromagnetic waves to generate Doppler signal measurements; an ECG unit mounted in the case in electrical connection with the ECG electrodes and configured to capture an ECG signal of the patient's heart to generate ECG signal measurements; an acceleration sensor mounted in the case and configured to at least one of generate an acceleration sensor signal indicative of posture and activity of the patient; and a monitoring unit configured to detect cardiac decompensation of congestive heart failure by comparing the Doppler and ECG signal measurements with a template which is adjusted in accordance with the acceleration sensor signal and a heart rate derived from the ECG signal measurements.
