METHOD AND SYSTEM FOR SECOND PASS CONFIRMATION OF AN ARRHYTHMIC EPISODE

Abstract: computer implemented methods and systems for detecting noise in cardiac activity are provided. the method and system obtain a far field cardiac activity (ca) data set that includes far field ca signals for a series of beats, overlay a segment of the ca signals with a noise search window, and identify turns in the segment of the ca signals. the method and system determine whether the turns exhibit a turn characteristic that exceed a turn characteristic threshold, declare the segment of the ca signals as a noise segment based on the determining operation, shift the noise search window to a next segment of the ca signal and repeat the identifying, determining and declaring operations; and modify the ca signals based on the declaring the noise segments.
