Abstract:
1. An electrotherapy device, comprising: a first sensor, that is adapted to be external to and adapted to be placed on a patient, and configured to sense a phonocardiogram (PCG) signal in the patient; a second sensor, that is adapted to be external to and adapted to be placed on the patient, and configured to receive an impedance-sensing signal from the patient; an electrotherapy generator, that is external to the patient, and is configured for delivering pacing stimuli to the patient through a skin of the patient; and processing circuitry, that is adapted to be external to the patient, and configured to analyze each of the PCG and impedance-sensing signals for features indicative of a presence of a cardiac pulse and determine based on each of the features indicative of a presence of a cardiac pulse, whether the cardiac pulse occurred in the patient following the delivery of a pacing stimulus of the pacing stimuli to the patient the processing circuitry increasing a current of further pacing stimuli to be delivered to the patient if the cardiac pulse did not occur in the patient following the delivery of the pacing stimulus.
