Abstract
Systems, methods, and interfaces are described herein for assisting a user in noninvasive evaluation of patients for cardiac therapy and noninvasive evaluation of cardiac therapy being delivered. The systems, methods, and interfaces may provide graphical representations of cardiac electrical activation times about one or more portions of human anatomy and one or more cardiac health metrics.
Claims20
A system for assisting in noninvasive evaluation of a patient for cardiac therapy comprising:
- electrode apparatus comprising a plurality of external surface electrodes positioned in an array, wherein the electrode apparatus is configured to locate the plurality of external surface electrodes proximate the skin of the patient;
- a display apparatus comprising a graphical user interface configured to present cardiac electrical activation time information and cardiac health information;
- and
- computing apparatus coupled to the electrode apparatus and the display apparatus and configured to provide the graphical user interface displayed on the display apparatus to assist a user in noninvasively evaluating the patient for cardiac therapy, wherein the computing apparatus is further configured to:
- noninvasively monitor electrical activity using one or more external surface electrodes of the plurality of external surface electrodes of the electrode apparatus proximate the patient's skin and proximate the patient's heart without use of an implantable device,
- measure surrogate cardiac electrical activation times using the noninvasively monitored electrical activity, wherein the surrogate cardiac electrical activation times are representative of depolarization of cardiac tissue that propagates through the torso of the patient,
- display, on the graphical user interface, a map of electrical activation based on the measured surrogate cardiac electrical activation times,
- measure at least one metric of the patient's cardiac health using one or both of the noninvasively monitored electrical activity and the measured surrogate cardiac electrical activation times, and
- display, on the graphical user interface, the at least one metric of the patient's cardiac health.

A computer-implemented method for assisting in noninvasive evaluation of a patient for cardiac therapy, the method comprising:
- noninvasively monitoring surrogate cardiac electrical activation times using one or more external surface electrodes proximate the skin of a patient and proximate the patient's heart without use of an implantable device, wherein the surrogate cardiac electrical activation times are representative of depolarization of cardiac tissue that propagates through the torso of the patient;
- measuring surrogate cardiac electrical activation times using the noninvasively monitored electrical activity, wherein the surrogate cardiac electrical activation times are representative of depolarization of cardiac tissue that propagates through the torso of the patient;
- displaying, on a graphical user interface, a graphical depiction of a portion of human anatomy and a map of electrical activation about the portion of human anatomy based on the measured surrogate cardiac electrical activation times;
- measuring at least one metric of the patient's cardiac health using one or both of the noninvasively monitored electrical activity and the measured surrogate cardiac electrical activation times;
- and
- displaying, on the graphical user interface, the at least one metric of the patient's cardiac health.
