Abstract
A method includes receiving heartbeat data of a patient and receiving activity data of the patient. The activity data includes one or more activity values that are related to an activity level of the patient and that are measured independently of the heartbeat data. The method further includes determining a value of a weighting factor based on the activity data. The method also includes determining modified heartbeat data by applying the weighting factor to at least a portion of the heartbeat data. The method also includes detecting a seizure event based on the modified heartbeat data.
Claims21
A method comprising:
- receiving heartbeat data of a patient;
- receiving activity data of the patient, wherein the activity data includes one or more activity values that are related to an activity level of the patient and that are measured independently of the heartbeat data;
- determining a value of a weighting factor based on the activity data;
- determining modified heartbeat data by applying the weighting factor to at least a portion of the heartbeat data;
- and
- detecting a seizure event based on the modified heartbeat data.
A medical device comprising:
- a first interface to receive heartbeat data of a patient;
- a second interface to receive activity data of the patient, wherein the activity data includes one or more activity values that are related to an activity level of the patient and that are measured independently of the heartbeat data;
- and
- a processor configured to:
- determine a value of a weighting factor based on the activity data;
- determine modified heartbeat data by applying the weighting factor to at least a portion of the heartbeat data;
- and
- detect a seizure event based on the modified heartbeat data.
A non-transitory computer-readable medium storing instructions that are executable by a processor to cause the processor to perform operations including:
- receiving heartbeat data of a patient;
- receiving activity data of the patient, wherein the activity data includes one or more activity values that are related to an activity level of the patient and that are measured independently of the heartbeat data;
- determining a value of a weighting factor based on the activity data;
- determining modified heartbeat data by applying the weighting factor to at least a portion of the heartbeat data;
- and
- detecting a seizure event based on the modified heartbeat data.
