METHOD AND SYSTEM FOR DETERMINING PACING SETTINGS

摘要

Systems and methods for optimizing the stimulation of a heart of a patient are disclosed herein. The method comprises delivering pacing therapy to the patient according to a pacing therapy setting schedule, using specific pacing intervals via specific electrode configurations. Further, sinus rate values are recorded over at least one cardiac cycle at each pacing therapy setting and it is determined whether a sinus rate value satisfies predetermined measurement conditions, wherein sinus rate values are used for trending the sinus rate over time if the measurement conditions are satisfied. The accepted sinus rate values, i.e. values that satisfy the measurement conditions, are trended over time, wherein each trended sinus rate value is created based on recordings from at least one cardiac cycle. A preferred pacing therapy setting is determined to be the pacing therapy setting that provides a lowest sinus rate.

1. A method for pacing therapy optimization of a cardiac stimulator implanted in a patient, the method comprising:
delivering cardiac pacing stimulation using specific pacing intervals via specific electrode configurations, over a range of cardiac pacing therapy settings; recording sinus rate values over at least one cardiac cycle at each cardiac pacing therapy setting; determining whether a sinus rate value satisfies predetermined measurement conditions; trending the sinus rate over time using sinus rate values satisfying the measurement conditions; and determining a preferred cardiac pacing therapy setting providing a lowest sinus rate based on a trend analysis of the sinus rate.
