Embodiments of the present disclosure generally relate wearable patches having rigid inserts. The rigid insert is positioned adjacent to one or more connectors, such as studs for receiving sockets to distribute the force transferred to a patient when reconnecting a socket to the stud. The rigid insert may be sized to maintain flexibility in areas of the wearable patch. An optional adhesive layer may be applied to the wearable patch adjacent the rigid insert to reduce the likelihood of delamination of the wearable patch.

Ambulatory medical devices may occasionally improperly administer a therapeutic stimulation pulse to a patient upon an incorrect detection of arrhythmia in the patient. To address these improperly administered therapeutic stimulation pulses, an ambulatory medical device includes processes and systems for verifying an initial declaration of an arrhythmia. The ambulatory medical device described include at least one first sensing electrode and at least one second sensing electrode distinct from the at least one first sensing electrode. First electrocardiogram (ECG) signals detected by the first sensing electrode are analyzed to provide an initial declaration of the arrhythmia condition of the patient. As a treatment protocol is being initiated in response to the analysis of the first ECG signals, second ECG signals detected by the second sensing electrode are analyzed to verify the initial declaration of the arrhythmia.

A method of measuring bioelectric signals of a patient having an axis extending from the patient's head to the patient's feet includes attaching a patch to the patient's skin. The patch may include a first electrode and a second electrode spaced apart along a longitudinal axis of the patch. The patch may be attached such that the longitudinal axis of the patch is generally aligned with the axis of the patient. The method may also include attaching a third electrode to the patient's skin, and measuring bioelectric signals of the patient using the first electrode, the second electrode, and the third electrode.

The present invention relates to a non-invasive cardiac monitoring device that records cardiac data to infer physiological characteristics of a human, such as cardiac arrhythmia. Some embodiments of the invention allow for long-term monitoring of physiological signals. Further embodiments allow for processing of the detected cardiac rhythm signals partially on the wearable cardiac monitor device, and partially on a remote computing system. Some embodiments include a wearable cardiac monitor device for long-term adhesion to a mammal for prolonged detection of cardiac rhythm signals.

A health monitor, comprising: an electrode that includes a hydrogel composition comprising a first network that comprises at least two hydroxyl-bearing chains of a first polymer, the at least two hydroxyl-bearing polymer chains being crosslinked by crosslinks that comprise one or more boronic ester bonds; and at least one conductive additive dispersed within the composition, the electrode being configured for patient contact. Also provided are related methods.
