Garments for wearable medical devices

A two-piece wearable cardiac monitoring device for monitoring a cardiac condition of a patient and optionally providing therapy to address arrhythmias, comprising:

• a garment configured to be worn about a torso of the patient;
• a plurality of ECG sensing electrodes configured to sense an ECG signal of the patient, the plurality of ECG sensing electrodes configured to be permanently or removably coupled to the garment;
• ECG sensor circuitry integrated into the garment and in communication with the plurality of ECG sensing electrodes;
• conductive wiring woven into the garment, the conductive wiring configured to facilitate the communication between the plurality of ECG sensing electrodes and the ECG sensor circuitry;
• at least one separable therapy delivery component comprising
• one or more energy storage modules;
• and
• a therapy control module in electrical communication with the one or more energy storage modules;
• an electrical connector disposed in the garment and configured to facilitate electrical coupling of the at least one separable therapy delivery component within the wearable cardiac monitoring device;
• and
• at least one processor operably connected to the ECG sensor circuitry, the at least one processor configured to
• receive one or more processed ECG signals from the ECG sensor circuitry,
• monitor for one or more arrhythmias based on the processed ECG signals,
• on detecting separation of the at least one separable therapy delivery component, cause the wearable cardiac monitoring device to automatically operate as a monitoring device, and
• on detecting installation of the at least one separable therapy delivery component, cause the wearable cardiac monitoring device to operate as a treatment device by further providing one or more therapeutic shocks to the patient in response to an arrhythmia of the monitored one or more arrhythmias.
