Systems and methods for detecting medical treatment
First Claim
1. A system for detecting a previous or ongoing treatment of a subject, the system comprising:
- a first physiologic sensor configured to sense a physiologic signal from the subject; and
a previous treatment detection circuit, the treatment detection circuit including;
a memory circuit configured to store information about the physiologic signal from the first physiologic sensor; and
a processor circuit configured to identify a candidate previous treatment event for the subject using the information about the physiologic signal stored in the memory circuit.

Abstract
Systems and methods are provided for using stored physiologic information about a subject to detect a previous treatment event. Physiologic information can be sensed from a subject using one or more sensors. Using a detection circuit, a change in the sensed physiologic information, such as a change from reference physiologic information, can be used to identify a candidate previous treatment event. An alert or other information about the candidate treatment event can be provided to a patient or clinician. In an example, a candidate treatment event can include a heart failure or diuresis treatment that is identified using information about a change in one or more of a subject'"'"'s circadian pattern, a subject'"'"'s thoracic impedance, or a subject'"'"'s respiration status.

12. A method for detecting a previous or ongoing treatment of a subject, the method comprising:
-
receiving, using an ambulatory medical device, physiologic status information about the subject over a first duration from a first physiologic sensor; recording the received physiologic status information about the subject using a memory circuit coupled to the ambulatory medical device; and identifying a candidate previous treatment event for the subject using a processor circuit and the recorded physiologic status information about the subject from the memory circuit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A system comprising:
-
an ambulatory medical device, comprising; a data input configured to receive a physiologic signal from a physiologic sensor, the physiologic sensor configured to sense information about a subject'"'"'s physiologic status; a memory circuit configured to store information about the physiologic signal received using the data input; and a processor circuit configured to identify a candidate previous heart failure treatment event using the information about the physiologic signal stored in the memory circuit; wherein the processor circuit is configured to identify a likelihood that the identified candidate previous heart failure treatment event indicates an actual previous heart failure treatment event; and wherein the processor circuit is configured to generate a treatment alert that includes physiologic signal information other than the information about the physiologic signal used by the processor circuit to identify the candidate previous treatment event.
