From: Software algorithm and hardware design for real-time implementation of new spectral estimator

Spectral estimates using the offline (panels A and C) and real-time (panels B and D) NSE software algorithm. Data used for analysis was acquired from the same patient at the antrum of the pulmonary veins–left superior (panels A and B) and left inferior (panels C and D). Overlap between offline and real-time traces is shown in panels E and F.
