    Abstract: A non-invasive medical device includes a garment; at least one therapy electrode and a plurality of ECG sensing electrodes disposed in the garment; a memory storing ECG information of the patient; a therapy delivery interface; and at least one processor configured to identify, within the ECG information, at least one cardiac arrhythmia condition; determine at least one pacing routine corresponding to the detected cardiac arrhythmia condition; cause the therapy delivery interface to execute the at least one pacing routine by delivering a first pacing pulse; determine, subsequent to the first pacing pulse, that a first interval has passed without detection of an intrinsic heartbeat, and in response, cause the therapy delivery interface to continue executing the at least one pacing routine by delivering a second pacing pulse; and responsive to determining that the intrinsic heartbeat is detected within the first interval, suspend execution of the at least one pacing routine.

    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.

    Abstract: A cardiac monitoring system includes cardiac sensing electrodes for external placement proximate to the patient to sense ECG signals of the patient; one or more accelerometers configured to generate patient activity data based on signals corresponding to changes in the patient's body position and movement; and a monitoring computer configured to correlate the ECG signals of the patient with the patient activity data generated from the one or more accelerometers to determine ECG signal contamination, analyze the ECG signals of the patient to extract at least heart rate data of the patient and detect a cardiac arrhythmia based at least in part on the heart rate data, and change a confidence in the detected cardiac arrhythmia based on the determined ECG signal contamination; wherein at least the patient activity data and the heart rate data are analyzed to determine a change in a physiological condition of the patient over time.

    Abstract: A system and method for conservation of battery power in a portable medical device is provided. In one example, a processor arrangement includes a dual core processor having an ARM core and a DSP core. The portable medical device includes a monitor having the dual core processor, in communication with a belt node processor. The DSP core receives physiological data from the physiological sensor and sends the physiological data to the ARM core. The ARM core analyzes the physiological data to determine if a treatment sequence is necessary. The DSP core receives physiological data from the at least one physiological sensor and sends the physiological data to the ARM core, and also analyzes the physiological data to determine proper timing of the treatment sequence by the at least one therapy delivery device to synchronize at least one pulse of the treatment sequence with the physiological data.
