Abstract
We report a method of detecting a pathological body state of a patient, comprising receiving a body signal of the patient; determining a BDV from said body signal; determining an activity level of said patient; determining a value range for said BDV for said patient, based at least in part on said activity level; comparing said BDV to said value range; and detecting a pathological state when said BDV is outside said value range. We also report a medical device system configured to implement the method. We also report a non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform the method.
Claims19
A method for detecting a pathological body state of a patient, comprising:
- receiving a first body signal of the patient;
- determining a first body data variability (BDV) from said first body signal;
- determining an activity level of said patient;
- determining a non-pathological range for said first BDV, based at least in part on said activity level;
- comparing said first BDV to said non-pathological range for said first BDV;
- detecting a pathological body state when said first BDV is outside said non-pathological range;
- and
- performing, in response to detecting said pathological state, at least one further action selected from issuing a notice of said detecting, delivering a therapy, issuing a warning, determining a severity of said pathological state, logging a time of occurrence of said detecting, logging a response to a therapy, and logging said severity of said pathological state.
A medical device system, comprising:
- at least one sensor, each said sensor configured to collect at least one body signal from a patient;
- an activity level module configured to determine an activity level of said patient, based at least in part on said at least one body signal;
- a current BDV module configured to determine at least a first BDV based on said at least one body signal;
- a BDV range determination module, configured to determine a non-pathological BDV range for said at least a first BDV, based at least in part on said activity level;
- and
- a pathological state determination module, configured to determine that the patient is in a pathological state if said at least first BDV is outside said non-pathological BDV range for said at least first BDV.
A method, comprising:
- receiving a first body signal of the patient;
- determining a change in a first body data variability (BDV), based on said first body signal;
- determining an activity level of said patient;
- determining if said change in said first BDV is commensurate with said determined activity level;
- and,
- taking a further action in response to determining that said change in said first BDV is incommensurate with said determined activity level.
