Abstract: Systems and methods are described herein for evaluation and adjustment cardiac therapy. The systems and methods may initially evaluate a first pacing parameter while other pacing parameters are fixed to, for example, nominal values, and determine an effective setting for the first pacing parameter. Then, a second pacing parameter may be evaluated while the first pacing parameter is fixed to the previously-determined effective setting. Each evaluation may not test every possible setting for the pacing parameters, and instead, may utilize various processes to limit the settings to a subset of settings to test.

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.

Abstract: Systems and methods are described herein for detecting disturbances in cardiac signals. An electrode apparatus includes a plurality of external electrodes to be disposed proximate a patient's skin. A computing apparatus includes processing circuitry. The computing apparatus is operably coupled to the electrode apparatus. The computing apparatus is configured to monitor electrical activity from tissue of a patient using a plurality of external electrodes to generate a plurality of electrical signals. At least one of the electrical signals of the plurality of electrical signals is filtered. At least one disturbance in the at least one electrical signal is detected using the at least one filtered signal. A temporal location of the at least one disturbance in the at least one electrical signal is determined based on a time that the at least one filtered signal crosses a predetermined threshold.
