Systems, devices and methods for monitoring efficiency of pacing
First Claim
1. A method for assessing a pacing location in a right ventricle of a heart and on a septum near a His bundle of a patient, the method comprising:
- delivering a pacing signal to the location in the right ventricle of the heart and on the septum near the His bundle;
monitoring a capture of a left ventricle of heart, the capture produced by the pacing signal, andassessing, using the monitored capture, the effectiveness of the delivered pacing signal as a function of at least one of a QRS width, fractionation and a timing of electrical stimulation activating a late activation site of a left ventricle, and using the assessment of the effectiveness of the delivered pacing signal for selecting a pacing parameter for use in delivering a pacing signal to a location of the heart on the septum near the His bundle.

Abstract
Various systems, methods, devices and arrangements are implemented for use in pacing of the heart. One implementation is directed to methods and systems for determining a pacing location in the right ventricle of a heart and near the His bundle. A pacing signal is delivered to the location in the right ventricle. The pacing signal produces a capture of a left ventricle. Properties of the capture are monitored. Results of the monitored capture are used to assess the effectiveness of the delivered pacing signal as a function of heart function. The heart function can be, for example, at least one of a QRS width, fractionation and a timing of electrical stimulation of a late activation site of a left ventricle relative to the QRS.

18. A method for assessing a pacing location in a right ventricle of a heart and on a septum near a His bundle of a patient, the method comprising:
-
delivering a pacing signal to the location in the right ventricle of the heart and on the septum near the His bundle; monitoring a capture of a left ventricle of heart, the capture produced by the pacing signal, and assessing, using the monitored capture, the effectiveness of the delivered pacing signal as a function of QRS width, fractionation, and a timing of electrical stimulation activating a late activation site of a left ventricle relative to the QRS, the assessing comprising comparing relative heart function between two or more monitored captures of the left ventricle of the heart providing an indication of the assessment from a processor arrangement to a user; using the assessment of the effectiveness of the delivered pacing signal for at least one of (1) selecting a pacing parameter for use in delivering a pacing signal to a location of the heart on the septum near the His bundle, and (2) selecting a location of the heart and on the septum near the His bundle for delivering a pacing signal. - View Dependent Claims (19, 20, 21)
