Figure 4From: Signal-averaged P wave analysis for delineation of interatrial conduction – Further validation of the method Median error in P wave duration as a result of recording length. Median error (%) in the P wave duration estimate as a result of recording length. L1 = 6 min; L2 = 3 min; L3 = 1 min; L4 = 30 s; L5 = 10 s, and L6 = 10 s recording length with lower sampling resolution (see text).Back to article page
