Description

Modular wearable medical device The present application is a divisional application of the application having the application date of 2016, 11 and 21, the application number of 201680060591.9, and the name of "clothing for wearable medical device". Cross Reference to Related Applications The present application claims priority from U.S. provisional application Ser. No. 62/258,666 entitled "GARMENTS FOR WEARABLE MEDICAL DEVICES," filed 11/23/2015, the entire contents of which are incorporated herein by reference for all purposes. Technical Field The present disclosure relates to garments for wearable medical devices including, for example, wearable monitoring devices and/or wearable therapeutic devices. Background There are a wide variety of electronic and mechanical devices for monitoring and treating a patient's medical condition. In some examples, a medical device such as a cardiac pacemaker or defibrillator may be surgically implanted in the patient or connected to the patient from outside the body, depending on the underlying medical condition being monitored or treated. In some cases, a physician may use a medical device alone or in combination with medication to treat a medical condition of a patient. One of the most deadly arrhythmias is ventricular fibrillation that occurs when normal and regular electrical impulses are replaced by irregular and rapid impulses, which causes the heart muscles to stop contracting normally and begin to vibrate. Normal blood flow ceases and organ damage or death may result within minutes if normal systole is not restored. Death often occurs before the necessary medical assistance can be reached because the victim has no perceptible warning of impending fibrillation. Other arrhythmias may include an excessively slow heart rate known as bradycardia. Implantable or external pacemakers and defibrillators, such as automatic external defibrillators or AEDs, etc., have significantly improved the ability to treat these otherwise life threatening conditions. These devices operate by applying a corrective electrical pulse directly to the patient's heart. Bradycardia can be corrected, for example, by using an implantable or extracorporeal pacemaker device. Ventricular fibrillation can be treated with implantable or external defibrillators. External pacemakers, defibrillators, and other medical monitors designed for outpatient and/or long-term use have further improved the ability to timely detect and treat life threatening conditions. For example, certain medical devices operate by continuously or substantially continuously monitoring a treatable arrhythmia in a patient's heart via one or more sensing electrodes, and in the event such treatable arrhythmia is detected, the device applies corrective electrical pulses directly to the heart via one or more therapy electrodes. Disclosure of Invention According to at least one aspect, a wearable heart device is provided. The wearable heart device includes a garment to be worn on a torso of a patient, the garment having at least a front portion and a back portion, at least one sensing electrode configured to monitor heart activity of the patient, at least one therapy electrode configured to provide therapy to the patient, and a controller. The controller may be configured to detect a heart condition of the patient based on the monitored heart activity of the patient and provide therapy to the patient based on the detected heart condition, the controller including a plurality of modules configured to be integrated into the garment and distributed throughout the garment. It should be appreciated that at least one of the at least one sensing electrode and the at least one therapy electrode may be configured to be integrated into the garment. In some examples, the garment includes at least one of a vest to be worn on the patient's upper body, a wraparound garment, and a shoulder strap. In some examples, the garment includes a single shoulder garment configured to be worn over one shoulder of the patient and to enclose an upper torso. In some examples, the garment is configured to be machine washable. In some examples, the garment is configured to be water resistant. In some examples, the garment includes a material that is less skin irritating. In some examples, the plurality of modules are distributed throughout the garment by weight to achieve a uniform weight distribution. In some examples, one or more of the plurality of modules is permanently secured into the garment. In some examples, one or more of the plurality of modules is configured to be removably secured into the garment. In some examples, one or more of the plurality of modules is configured to be secured within a respective one or more pockets provided in the garment. In some examples, one or more of the plurality of modules is configured to be removably secured to the garment. In some examples, one or more of the plurality of modules is configured to be slidably secured to th
