First Claim
Patent Images
1. An implantable system for capturing data about potential syncope events, the system comprising:
- a cardiac sensor that captures signals from the patient'"'"'s body indicative of the function of the patient'"'"'s heart;
a seizure sensor that captures signals from the patient'"'"'s body indicative of potential seizure activity of the patient;
a hemodynamic sensor that captures signals from the patient'"'"'s body indicative of the hemodynamic performance of the patient'"'"'s body; and
a processor that receives the signals from the cardiac sensor, the seizure sensor and the hemodynamic sensor, so that the signals detected by the cardiac sensor, the seizure sensor and the hemodynamic sensor can be evaluated to assess potential causes of syncope events.

Abstract
A multi-channel implantable syncope monitor that monitors ECG data, myopotential data, EEG data, photoplethysmography (PPG) data, and position sensor data is used to capture physiologic data about a patient who is experiencing a syncopal event. The timing of the events within the simultaneously captured physiologic data can then be used to more accurately determine potential sources of origin of the syncopal event.

12. An implantable system for capturing data about potential syncope events, the system comprising:
-
a plurality of sensors that sense a plurality of different physiologic characteristics of the patient, including physiologic characteristics indicative of cardiac performance, seizure activity and hemodynamic function; and a processor that simultaneously receives signals from the plurality of sensors wherein the processor evaluates the signals from the plurality of sensors so that the relative timing of events detected by the plurality of sensors can be used to ascertain possible sources of potential syncope events. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of monitoring physiological signals relating to potential sources of syncope-related events, the method comprising:
-
implanting a plurality of sensors within the body of a patient that monitor a plurality of different physiologic parameters including hemodynamic status, heart rate and seizure activity; simultaneously capturing signals from the plurality of sensors; and comparing the relative timing of events in the captured signals to ascertain potential sources of syncope-related events. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
