Abstract
This document discusses, among other things, systems and methods to receive cardiac electrical information of a subject, detect a premature ventricular contraction (PVC) event in a first detection window using the received cardiac electrical information, determine a count of detected PVC events in the first detection window, remove cardiac electrical information associated with the detected PVC event from the first detection window based on the determined count of detected PVC events, and detect an indication of atrial fibrillation of the subject for the first detection window using remaining cardiac electrical information in the first detection window.
Claims20
A system, comprising:
- a signal receiver circuit configured to receive cardiac electrical information of a subject;
- and
- an assessment circuit configured to:
- detect a premature ventricular contraction (PVC) event in a first detection window using the received cardiac electrical information from the first detection window;
- determine a count of detected PVC events in the first detection window;
- remove cardiac electrical information associated with the detected PVC event from the first detection window based on the determined count of detected PVC events;
- and
- detect an indication of atrial fibrillation of the subject for the first detection window using remaining cardiac electrical information in the first detection window.
A method, comprising:
- receiving, using a signal receiver circuit, cardiac electrical information of a subject;
- detecting, using an assessment circuit, a premature ventricular contraction (PVC) event in a first detection window using the received cardiac electrical information from the first detection window;
- determining, using the assessment circuit, a count of detected PVC events in the first detection window;
- removing, using the assessment circuit, cardiac electrical information associated with the detected PVC event from the first detection window based on the determined count of detected PVC events;
- and
- detecting, using the assessment circuit, an indication of atrial fibrillation of the subject for the first detection window using remaining cardiac electrical information in the first detection window.
A system, comprising:
- a signal receiver circuit configured to receive cardiac electrical information of a subject;
- and
- an assessment circuit configured to:
- detect a premature ventricular contraction (PVC) event using the received cardiac electrical information;
- detect, using the received cardiac electrical information, an indication of atrial fibrillation of a subject using one of multiple atrial fibrillation detection modes, each of the multiple atrial fibrillation detection modes configured to detect atrial fibrillation of the subject;
- determine a count of detected PVC events in a first detection window;
- and
- transition between different first and second atrial fibrillation detection modes of the multiple atrial fibrillation detection modes based on the determined count of PVC events in the first detection window.
