System and method for monitoring and diagnosing patient condition based on wireless sensor monitoring data
First Claim
1. A method of managing a heart condition for a subject, the heart condition comprising one or more of ventricular arrhythmia, atrial arrhythmia, ventricular fibrillation, ventricular tachycardia, atrial fibrillation, and bradycardia, the method comprising:
- (a) detecting intrathoracic electrogram signals of the subject over a first defined period of time by at least one implantable cardiac device having a sensor component implanted in the heart of the subject;
(b) determining whether the subject is experiencing a heart condition based on the electrogram signals;
(c) detecting ECG signals of the subject over the first defined period of time by at least one surface sensor attached to the skin of a subject,(d) determining whether the subject is experiencing the heart condition based on the ECG signals;
(e) based upon the results of each of steps (b) and (d), determining whether to provide an electrical stimulation to influence an electrical system of the heart of the subject in order to address the heart condition; and
(f) performing, by the implantable cardiac device, the electrical stimulation if the determination result in step (e) is positive;
(g) wirelessly sending, by the at least one implantable cardiac device, selected information relating to at least one of the electrogram signals in step (a), the determination result in step (b) and the determination result in step (e) to the at least one surface sensor; and
(h) wirelessly sending, by the at least one surface sensor, the information received from the at least one implantable cardiac device, as well as selected information relating to at least one of the ECG signals in step (c) and the determination result in step (d), to an external computing device for storage or further analysis.

Abstract
A device adapted to attach to a subject for detecting an ECG signal of the subject. The device includes a first, a second, and a third electrode, where the electrodes form an orthogonal configuration. Two channels of ECG data can be obtained using a common electrode, and can be further combined to obtain a further channel using vector mathematics. The channel combination can be performed at vector angles suitable for optimizing the detection of various features of the ECG spectra of the subject. A method of using an implantable cardiac device together with surface-attached wireless sensor(s) is also provided where the acquired data from the implantable cardiac device and from the surface-attached wireless sensor(s) are both used for diagnosing patient'"'"'s heart conditions and administering appropriate therapies.
