Abstract

A wearable cardioverter defibrillator (WCD) system comprises a plurality of patient parameter electrodes and a plurality of defibrillator electrodes to contact a patient's skin when the WCD is delivering therapy to the patient, a processor to receive one or more patient parameters from the one or more patient parameter electrodes, an energy storage device to store a charge to provide electrical therapy to the patient via the plurality of defibrillator electrodes, and a non-invasive blood pressure (NIBP) monitor to obtain a blood pressure measurement of the patient and to provide the blood pressure measurement to the processor. The processor is to determine whether to provide electrical therapy to the patient based on the one or more patient parameters during an episode, and to obtain the blood pressure measurement from the NIBP monitor during the episode.
