Abstract
A data collection system collects and stores physiological data from an ambulatory patient at a high resolution and/or a high data rate (“more detailed data”) and sends a low-resolution and/or downsampled version of the data (“less detailed data”) to a remote server via a wireless network. The server automatically analyzes the less detailed data to detect an anomaly, such as an arrhythmia. A two-tiered analysis scheme is used, where the first tier is more sensitive and less specific than the second tier. If the more sensitive analysis detects or suspects the anomaly, the server signals the data collector to send more detailed data that corresponds to a time period associated with the anomaly. The more specific second tier analyses the more detailed data to verify the anomaly. The server may also store the received data and make it available to a user, such as via a graphical or tabular display.
Core Innovation
The invention relates to an electrocardiogram (ECG) monitoring system for an ambulatory patient, where physiological sensor data including ECG data is collected locally. The system stores received data in at least one memory and periodically transmits a first subset of the received data to a remotely-located data analyzer according to a preset duty cycle, using at least one wireless transceiver.
Separate from the preset duty cycle, the remotely-located data analyzer provides a request that includes a change in one or more of a data collection parameter and/or a data transmission parameter of the ECG monitoring system. In response, the controller changes the one or more parameters and, via the wireless transceiver, transmits a second subset of the received data to the remotely-located data analyzer.
The first and second subsets can be characterized by different levels of detail, with the second subset including more detailed data than the first subset. The requested change can relate to sampling rate and/or sampling precision and can also relate to transmission-related parameter characteristics such as transmission packet size, packet transmission rate, and number of samples per packet, as specified by dependent claim refinements.
In some implementations, the system automatically determines when a sensor measurement exceeds a predetermined threshold and, in response, adjusts at least one data collection parameter or data transmission parameter. The controller and/or memory can be included in a mobile phone with a wireless operative connection between the sensor and the controller, and the received and transmitted data can be retained for display-related use as further refined by dependent claims.
Claims Coverage
The independent claims are directed to an ECG monitoring system, a method of operating the ECG monitoring system, and a non-transitory computer readable medium. Across these independent claims, the core coverage contains a two-subset data communication framework with remote analyzer-controlled, request-driven changes to data collection and transmission parameters (including the capability to change the type of data subset sent).
Remote request-driven parameter change for second subset transmission
Separately from the preset duty cycle: receiving a request from the remotely-located data analyzer, wherein the request includes a change in one or more of a data collection parameter or a data transmission parameter of the ECG monitoring system; and in response: changing, via the controller, the one or more of the data collection parameter or the data transmission parameter of the ECG monitoring system based on the request; and via the at least one wireless transceiver, transmitting a second subset of the received data to the remotely-located data analyzer.
Preset duty-cycle transmission of a first subset to a remotely-located data analyzer
At a preset duty cycle and via the at least one wireless transceiver, periodically transmitting a first subset of the received data to a remotely-located data analyzer.
Local collection of sensor data including ECG data in memory
Receiving data from the at least one sensor, and collecting the received data in the at least one memory, the received data including ECG data.
Wireless sensor-to-controller data acquisition with controller-executed instructions
Receiving, at the controller of the ECG monitoring system and via a wireless transceiver operatively connected to the controller, data from at least one sensor operatively connected to the wireless transceiver, and collecting the received data in at least one memory of the ECG monitoring system, the received data including ECG data.
Controller-implemented method operations for first and second subset transmissions
At a preset duty cycle and via the at least one wireless transceiver, periodically transmitting, by the controller and via the wireless transceiver, a first subset of the received data to a remotely-located data analyzer; separate from the preset duty cycle receiving, at the controller and via the wireless transceiver, a request from the remotely-located data analyzer including a change in one or more of a data collection parameter or a data transmission parameter of the ECG monitoring system; and in response to receiving the request changing, via the controller, the one or more of the data collection parameter or the data transmission parameter based on the request; and transmitting, by the controller and via the wireless transceiver, a second subset of the received data to the remotely-located data analyzer.
Non-transitory computer readable medium with controller-executable instructions for request-driven subset updates
A non-transitory computer readable medium storing instructions executable by a controller to perform operations including receiving sensor data including ECG data via a wireless transceiver, periodically transmitting a first subset to a remotely-located data analyzer at a preset duty cycle, receiving (separate from the preset duty cycle) a request from the remotely-located data analyzer including a change in one or more of a data collection parameter or a data transmission parameter, changing the one or more parameters in response, and transmitting a second subset to the remotely-located data analyzer via the wireless transceiver.
The independent claims collectively require local collection of ECG sensor data, periodic transmission of a first subset to a remote analyzer according to a preset duty cycle, and separate reception of a remote analyzer request that changes data collection/transmission parameters so that a second subset is transmitted using the updated parameters. Dependent claim refinements further cover that the second subset can provide more detailed data and that the changed parameters can include sampling and packet-related characteristics, with optional threshold-triggered adjustments and mobile-phone-based implementation.
Stated Advantages
Enables changing data collection and/or data transmission parameters at the request of a remotely-located data analyzer so that a second subset is transmitted in response.
Allows providing different levels of detail between a first subset and a second subset, with the second subset including more detailed data.
Supports automatic adjustment of at least one data collection parameter or data transmission parameter when a sensor measurement exceeds a predetermined threshold.
Documented Applications
Remote ECG monitoring with periodic transmission of ECG data subsets to a remotely-located data analyzer and request-driven transmission of a second subset for verification of an anomaly as refined by the dependent claims (e.g., suspected arrhythmia tied to a time period).
