US Patent 11911168 Cardiac conduction system therapy benefit determination

Systems and methods are described herein for determining whether cardiac conduction system pacing therapy may be beneficial and/or determining how proximal or distal a cardiac conduction system block may be using external cardiac signals. To do so, one or more left-sided metrics of electrical heterogeneity information may be generated based on left-sided surrogate cardiac electrical measured using a plurality of left external electrodes.
