A blood pressure data display method includes following steps: (1) constituting the whole frame of each split screen while displaying by a split screen (S1) (2) setting index variables of single measurement data to be displayed and setting numbers of split screens to be displayed (S2) (3) reading a group of single measurement data (S3) (4) displaying the blood pressure date on the screen according to the set numbers of split screens and the read single measurement data (S4)(5) inputting a screen switch condition using an operation unit (S5,S7). The switch condition is one condition choosing from the following two conditions: (1) a first screen switch condition: which split screen number to be displayed (2) a second screen switch condition: which group of history measurement data to be displayed. If the first screen switch condition is inputted, after screen switch, the numbers of split screens to be displayed are determined according to the switch condition (S6) and it returns to step (4) If the second screen switch condition is inputted, after screen switch, the index variables of single measurement data to be displayed are determined according to the switch condition (S8) and it returns to step (3). The single measurement data can be displayed more visually by using this method, and the users can look up the history data in a fast and convenient manner.Linvention concerne un procédé daffichage de données de pression artérielle, qui comprend les étapes suivantes: 1) la constitution de la grille entière de chaque écran divisé au moment de laffichage par écran divisé (S1) 2) létablissement de variables dindice de données de mesure uniques devant être affichées, et létablissement de numéros décrans divisés à afficher (S2) 3) la lecture dun groupe de données de mesure uniques (S3) 4) laffichage des données de pression artérielle à lécran en fonction des numéros établis pour les écrans divisés et des données de mesure uniques lues (S4) 5) lintroduction dun paramètre de
