    Abstract: A wearable medical device for determining whether a patient is experiencing a cardiac event using electrocardiogram (ECG) templates includes a plurality of ECG electrodes and a medical device controller. The medical device controller includes a memory, a baseline generator, a cardiac event detector, and a mode selector. The baseline generator is configured to record a baseline ECG signal, generate one or more ECG templates, and store the one or more ECG templates in the memory. The cardiac event detector is configured to select an ECG template and compare a current ECG signal with the selected ECG template to determine whether the patient is experiencing a cardiac arrhythmia. The mode selector is configured to identify whether any ECG templates are stored in the memory, determine whether a new ECG template is needed, and, upon determining that a new ECG template is needed, enter a baselining mode by activating the baseline generator.

    Abstract: In some examples, an ambulatory medical device is provided. The ambulatory medical device includes at least one sensor configured to acquire data descriptive of the patient, one or more processors in communication with the at least one sensor, a patient care component executable by the one or more processors, and a limited functionality component executable by the one or more processors. The patient care component is configured to perform one or more primary operations of the ambulatory medical device at least in part by accessing the data descriptive of the patient. The limited functionality component is configured to exchange information with a communication device and to not affect the one or more primary operations of the ambulatory medical device.

    Abstract: A patient monitoring device configured to monitor cardiac activity and sleep stage information of a patient is provided. The device includes a plurality of electrodes to acquire electrocardiogram (ECG) signals from the patient, at least one motion sensor configured to generate a motion signal based upon movement of the patient, and at least one processor. The processor is configured derive motion parameters from the motion signal, derive ECG parameters from the ECG signals, determine whether the patient is in an immobilized sleep stage or a non-immobilized sleep stage based upon the motion parameters and the ECG parameters, adjust one or more cardiac arrhythmia detection parameters such that the device operates in a first monitoring and treatment mode when the patient is in an immobilized sleep stage, and monitor the patient for the cardiac arrhythmia using the first monitoring and treatment mode.
