Claim 0:
1. A patient-worn arrhythmia monitoring and treatment device, comprising:
at least one contoured pad configured to be adhesively coupled to a torso of a patient;
a plurality of therapy electrodes, at least one of which is integrated with the at least one contoured pad;
a plurality of ECG sensing electrodes, at least one of which is integrated with the at least one contoured pad;
at least one housing configured to form a watertight seal with the at least one contoured pad, the at least one housing extending no more than 5 cm from a surface of the at least one contoured pad;
an ECG acquisition and conditioning circuit disposed within the at least one housing and electrically coupled to the plurality of ECG sensing electrodes to provide at least one ECG signal of the patient;
a therapy delivery circuit disposed within the at least one housing and configured to deliver one or more therapeutic pulses to the patient through the plurality of therapy electrodes; and
a processor disposed within the at least one housing and coupled to the therapy delivery circuit and configured to
analyze the at least one ECG signal of the patient and detect one or more treatable arrhythmias based on the at least one ECG signal; and
cause the therapy delivery circuit to deliver at least one defibrillation pulse to the patient on detecting the one or more treatable arrhythmias,

wherein the patient-worn arrhythmia monitoring and treatment device has a weight between 250 grams and 2,500 grams,
wherein an assembly comprises the at least one housing, the ECG acquisition and conditioning circuit disposed within the at least one housing, the therapy delivery circuit disposed within the at least one housing, and the processor disposed within the at least one housing, and
wherein the assembly is configured such that a center of mass of the assembly is below a volumetric center of the assembly with respect to a vertical axis of the assembly when the device is mounted on the patient as the patient is standing or sitting.
