Abstract: A system for accounting for adverse pacing artifacts may include an electrode apparatus and a computing apparatus. The electrode apparatus may include one or more external electrodes to monitor electrical activity from tissue of a patient. The computing apparatus may include one or more processors and may be operatively coupled to the electrode apparatus. The computing apparatus may be configured to monitor electrical activity from the tissue of the patient using the one or more external electrodes. Such electrical activity may be used to generate one or more cardiac signals of the patient over time. The computing apparatus may detect a pacing artifact in the one or more cardiac signals and determine whether to account for, and account for, the pacing artifact based on a pacing artifact characteristic of the pacing artifact when producing electrical heterogeneity information.

Abstract: Systems and methods are described herein for generating representative cardiac information. The representative cardiac information may be based on a plurality of electrode signals monitored, or measured, over a plurality of cardiac cycles or heart beats. The systems and methods may remove unqualified cardiac cycles, remove invalid electrode signals, remove inconsistent cardiac cycles, and removing uncorrelated cardiac cycles, and then generate representative cardiac information based on the remaining cardiac cycles and electrode signals.

Abstract: Electrical activity from tissue of a patient is monitored using a plurality of external electrodes to generate a plurality of electrical signals over time. The plurality of electrical signals are filtered using a first filter having a first frequency range to generate a plurality of first filtered signals. The plurality of electrical signals are filtered using a second filter having a second frequency range different than the first frequency range to generate a plurality of second filtered signals. At least one QRS complex is detected based on the plurality of first filtered signals. A QRS peak of the at least one QRS complex is detected based on the plurality of second filtered signals and the detected at least one QRS complex.
