    Abstract: A wearable medical device for detecting and treating life-threatening arrhythmias includes a wearable vest portion, sensing electrodes, therapy pads, at least one motion sensor, and a cardiac monitor. The cardiac monitor is configured to detect whether the patient is experiencing a treatable arrhythmia using an ECG signal and in response, determine a confidence level for the detected treatable arrhythmia using outputs from the at least one motion sensor. Determining the confidence level includes detecting patient motion prior to the detection of the treatable arrhythmia. Determining the confidence level further includes increasing the confidence level in response to determining that the patient is motionless coinciding with the detection of the treatable arrhythmia, or decreasing the confidence level in response to determining the patient motion after the detection of the treatable arrhythmia. The cardiac monitor is configured to determine whether to deliver a treatment shock based on the confidence level.

    Abstract: A wearable defibrillator for monitoring treatable arrhythmias in a patient in the presence of background noise includes a plurality of sensing electrodes configured to generate ECG data, one or more therapy pads, one or more audio devices, and one or more processors. The one or more audio devices include a microphone configured to detect background noise and a speaker. The one or more processors are configured to determine, from at least the ECG data, whether the patient is experiencing a treatable arrhythmia; cause, via the speaker, an audible alarm in response to determining that the patient is experiencing the treatable arrhythmia; delay a delivery of treatment to the patient in response to determining that at least the predetermined level of background noise exists; and during the delay, perform at least one of obtaining additional data or running an additional test to verify that the patient is experiencing the treatable arrhythmia.

    Abstract: A wearable medical treatment device for monitoring a patient's ECG and treating a cardiac condition is disclosed. The device includes a patient vest portion having cardiac sensing electrodes to obtain an ECG signal of a patient, therapy electrodes for external placement proximate to skin of the patient for delivering electrotherapy to treat the cardiac condition, and, a monitor coupled to the cardiac sensing electrodes and the therapy electrodes via at least one cable. The monitor includes a system computer disposed in the monitor. The system computer is configured to receive the ECG signals of the patient and to execute at least one arrhythmia detection algorithm to determine whether the patient is experiencing a cardiac condition in need of treatment, and a mechanical shock detector disposed on the monitor and configured to detect at least one of a force or acceleration indicative of a mechanical shock to the monitor.
