WebMethods: One thousand four hundred thirty-five ECGs were randomly selected to determine the incidence and gender frequency in tracings showing positive (PPV 2 ), and biphasic (BPV 2 ) P waves in V 2 , as well as NPV 2 . To those cases with NPV 2 , 84 cases with that anomaly from earlier archived ECGs were added to give a larger group for analysis.
