In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one electrocardiogram (ECG) electrode, at least one acoustic sensor, and at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one therapy electrode. The at least one processor can receive at least one acoustic signal from the at least one acoustic sensor, receive at least one electrode signal from the ECG electrode, detect at least one unverified cardiopulmonary anomaly using the at least one electrode signal, and verify the at least one unverified cardiopulmonary anomaly with reference to data descriptive of the at least one acoustic signal.

Medical device with acoustic sensor

A system including a medical device is provided. The medical device includes at least one sensor configured to acquire first data descriptive of a patient, first memory storing a plurality of templates, and at least one processor coupled to the at least one sensor and the first memory. The at least one processor is configured to identify a first template of the plurality of templates that is similar to the first data, to determine first difference data based on the first template and the first data, and to store the first difference data in association with the first template. The system may further include the programmable device.

Systems and methods of patient data compression

Devices, systems, and methods for providing patient wear compliance information are provided. For example, a medical device includes a plurality of electrodes configured to be continuously coupled externally to a patient and to monitor electrical activity on the skin of the patient. The system also includes at least one motion sensor configured to generate a motion signal based upon movement of the patient. The system further includes a processor configured to receive an electrical signal based on the monitored electrical activity, record a wear onset event based on the electrical signal and the motion signal, record a wear offset event based on one or more of the electrical signal and the motion signal indicating that the patient is not wearing the medical device, and output a graphical representation including information regarding the patient's wear compliance based on the recorded wear onset event and the recorded wear offset event.

Systems and methods of monitoring wear compliance of a patient wearing an ambulatory medical device

A wearable defibrillator for use in monitoring patient movement and cardiac activity and treating a patient includes a garment configured to be worn by the patient, treatment electrodes configured to apply an electric current to the patient, and an alarm module configured to provide audio, visual, and haptic notifications. The notifications are configured to indicate that an electric current will be administered imminently and prompt the patient to provide a response input. The wearable defibrillator includes a motion sensor configured to detect motion and body position of a patient, and a controller in electrical communication with the alarm module and the motion sensor. The controller is configured to monitor for the response input after the prompt, determine, based on the detected motion and body position, whether the patient is sleeping, and cause a change in one or more characteristics of the prompt on determining that the patient is sleeping.

Wearable medical monitoring device

In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one acoustic sensor, and at least one processor coupled with the at least one therapy electrode and the at least one acoustic sensor. The at least one processor is configured to deliver at least one pacing pulse via the at least one therapy electrode and to analyze processed acoustic data to determine whether the at least one pacing pulse resulted in capture.

Pacing device with acoustic sensor

A method of determining responsiveness of a patient wearing a wearable defibrillator configured to deliver therapy to the patient includes sensing an electrocardiogram signal of the patient wearing the wearable defibrillator via a plurality of ECG sensing electrodes, and determining whether a defibrillation treatment should be provided to the patient via at least one treatment electrode. The method includes causing a user interface to provide a patient prompt from the wearable defibrillator responsive to determining that the defibrillation treatment should be provided to the patient. The method includes receiving a first signal indicative of a first patient response within a time interval, receiving a second signal indicative of a second patient response within the time interval, and withholding the defibrillation treatment to the patient via the at least one treatment electrode in response to receiving both the first signal and the second signal within the time interval.

Medical device configured to test for user responsiveness

A system includes an ambulatory medical device and a server. The ambulatory medical device comprises: a digital signal processing module configured to: detect an abnormal rhythm from an electrocardiogram (ECG) signal of a patient using a first signal processing routine; and generate a first flag indicating an abnormal rhythm is detected; and a noise detector module configured to: receive the ECG signal from the digital signal processing module; execute a second signal processing routine to classify the abnormal rhythm as one of an arrhythmia event and a noise event; and, if the abnormal rhythm is classified as a noise event, initiate a preconfirmation period during which the noise detector module continues to evaluate the abnormal rhythm and classify the abnormal rhythm as one of an arrhythmia event and a noise event using the second signal processing routine; and generate a second flag indicating the start of the preconfirmation period; and a server configured to: receive the ECG signal, the first flag indicating the abnormal rhythm, and the second flag indicating the start of the preconfirmation period; and provide a visual indication of the preconfirmation period.

System and method for distinguishing a cardiac event from noise in an electrocardiogram (ECG) signal

A wearable defibrillator includes garment configured to be worn by a patient, treatment electrodes configured to apply electric current to the patient, and an alarm module configured to provide audio, visual, and haptic notifications. The notifications are configured to indicate that an electric current will be administered imminently, and prompt the patient to provide a response input. The wearable defibrillator includes a motion sensor configured to detect motion and a lack of motion of the patient, and a controller in electrical communication with the alarm module and the motion sensor. The controller is configured to monitor for the response input, cause administration of the electric current to be delayed or cancelled if the response input is received and motion of the patient is detected, and cause administration of the electric current to be delivered if no response input from the patient is received and a lack of motion is detected.

A system for assigning zone rankings to a patient. The system includes a processor, at least one database, and a computer readable medium in communication with the at least one database and comprising one or more instructions that, when executed, can cause the processor to receive at least one physiological signal from a medical monitoring device that is worn by a patient; assign a normal zone ranking to the patient based upon historical patient data stored on the at least one database; determine one or more metrics from the at least one physiological signal of the patient; assign a first zone ranking to the patient based upon the one or more metrics, the first zone ranking selected from a plurality of abnormal zone rankings stored on the at least one database; determine one or more actions to initiate based upon the assigned first zone ranking; and initiate the one or more determined actions.
