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.

Abstract: A system for detecting an electrocardiogram (ECG) signal of a subject includes a substrate that is placed on and adheres to the skin over the sternum of the subject. First, second and third electrodes are disposed on the substrate, each of which has an end for contacting a respective area of skin. Directional positioning from the second electrode to the first electrode is substantially perpendicular to directional positioning from the third electrode to the first electrode. A circuit on the first substrate is connected to the electrodes and generates a first ECG channel measuring a difference in electric signals between the first electrode and the second electrode, and a second ECG channel measuring a difference in electric signals between the first electrode and the third electrode. A communication component on the substrate wirelessly transmits ECG information from the circuit to an external device.
