SYSTEMS AND METHODS TO DETERMINE HR, RR AND CLASSIFY CARDIAC RHYTHMS BASED ON ATRIAL IEGM AND ATRIAL PRESSURE SIGNALS

摘要

Systems, devices and methods described herein can be used to monitor and treat cardiovascular disease, and more specifically, can be used to determine heart rate (HR), determine respiration rate (RR) and classify cardiac rhythms based on atrial intracardiac electrogram (IEGM) and atrial pressure (AP) signals. The atrial IEGM and AP signals are subject to spectrum transforms to obtain an atrial IEGM frequency spectrum and an AP frequency spectrum. Based on peaks in the atrial IEGM and AP frequency spectrums measures of HR and RR are determined, and arrhythmias are detected and/or arrhythmia discrimination is performed.

1. A method, comprising:
(a) obtaining an atrial IEGM signal; (b) obtaining an atrial pressure (AP) signal indicative of pressure in an atrium; (c) subjecting the atrial IEGM signal to a spectrum transform to obtain an atrial IEGM frequency spectrum; (d) subjecting the AP signal to a spectrum transform to obtain an AP frequency spectrum; (e) determining a first measure of heart rate (HRIEGM) based on one or more peaks in the atrial IEGM frequency spectrum; and (f) determining a second measure of heart rate (HRAP) and a measure of respiratory rate (RRAP) based on one or more peaks in the AP frequency spectrum.
