A wearable cardioverter defibrillator (WCD) comprises a support structure to be worn by a patient, an energy storage module to store an electrical charge, a discharge circuit coupled to the energy storage module, a measurement circuit, a user interface that includes a speaker, and a processor. The processor is configured to monitor a physiological signal of a patient with the measurement circuit to detect cardiac arrythmia when the patient is wearing the support structure, determine whether a validation criterion is met in response to detection of a cardiac arrythmia, provide no alarm with the user interface the validation criterion is being determined, and cause a shock to be delivered to the patient from the energy storage module by the discharge circuit in the event the validation criterion is met

A garment for detecting physiological data. The garment may include a garment body and a primary sensor panel affixed to a user facing side of the garment body. The primary sensor panel may include at least one bio signal sensor type to generate a primary set of bio signals. The garment may include a processor coupled to the primary sensor panel and a memory coupled to the processor. The memory may store processor-executable instructions that, when executed, configure the processor to: receive, from the primary sensor panel, the primary set of bio signals; generate a bio signal waveform based on the primary set of bio signals; and determine a hemodynamic metric associated with the user based on the bio signal waveforms associated with the user.

A first layer (301) has an outer surface (302) facing away from the wearer and an inner surface (304) facing towards the wearer. The first layer (301) comprises a recess (303a, 303b). A sensing component (100a, 100b) is attached to he inner surface (304) and comprises fabric base component (101) and first and second conductive regions (109a, 109b, 111a, 111b). The base component (101) has an outer surface (105) facing the inner surface (304) and an inner surface (103) facing towards the wearer. The first conductive region (109a, 109b) is provided on the inner surface (103) and forms an electrode. The second conductive region (111a, 111b) is provided on the outer surface (105). The second conductive region (111a, 111b) is aligned with the recess (303a, 303b) in the first layer of material (301) and forms a connection terminal for connecting with an interface element of an electronics module (200).

Systems and methods are described herein for evaluation and adjustment cardiac therapy. The systems and methods may initially evaluate a first pacing parameter while other pacing parameters are fixed to, for example, nominal values, and determine an effective setting for the first pacing parameter. Then, a second pacing parameter may be evaluated while the first pacing parameter is fixed to the previously-determined effective setting. Each evaluation may not test every possible setting for the pacing parameters, and instead, may utilize various processes to limit the settings to a subset of settings to test.

A garment for measuring biological information equipped with an electrode and wiring, with which noise can be prevented from being mixed in to the biological electric signals to be read, and with which a wearer feels less discomfort, even under dry condition while the garment is worn. Static electrical charge generated while the garment is worn is suppressed to decrease the noise in the biological electric signals to be read by selecting a combination of electrically insulating materials constituting the garment that have smaller gap of frictional electrostatic voltage, as well as using the electrode and wiring that are stretchy and have high conductivity even when being stretched to reduce discomfort while the garment is worn.

A garment for measuring biological information, wherein the garment is configured such that when a wearer wears the garment, a conductive member is easily disposed at a desired position on the wearer, and even when the wearer moves his/her arm or raises his/her arm, the conductive member is less likely to be displaced from the desired position on the wearer. The garment has a torso portion and a stretchable conductive member being formed on the garment with an adhesive layer interposed therebetween.

A wearable cardioverter defibrillator (WCD) (10) and method (60) comprise a set of electrodes (12) for placement on a subject (14), a mechanism for electrically engaging (16) the set of electrodes to the subject's skin, and at least one non-invasive physiologic sensor (18, 20) configured for placement on the subject. A controller (24) monitors an output of the non-invasive physiologic sensor (18, 20) for detecting a change in a health parameter of the subject being indicative of one or more of a change in subject condition that may be a precursor to potential cardiac arrhythmia or a simultaneously occurring cardiac arrhythmia. Responsive to detecting the change, the controller (24) activates an alarm (26) for requesting a response from the subject (14) within a predetermined time. Responsive to receiving the subject's response within the predetermined time, the controller (24) inhibits the mechanism (16) from electrically engaging the set of electrodes (12) to the subject's skin. Responsive to not receiving the subject's response, the controller (24) initiates the mechanism (16) for electrically engaging the set of electrodes (12) to the subject's skin.

A wearable medical device is provided. The wearable medical device includes a garment that includes a sensing electrode, at least one of an inductive element and a capacitive element included in at least part of the garment, and a controller. The controller may be configured to determine a confidence level of information received from the sensing electrode based on at least one of an inductance of the inductive element and a capacitance of the capacitive element.
