Microcomputer-aided data logging and processing system was applied to 24-hr esophageal pH monitoring and its usefulness was evaluated. On 15 asymptomatic infants, the examination was undertaken with this system. The output of pH-meter was input into microcomputor (L-16A) via 8 bit A/D converter. The data were saved into casette MT every hourly for 24 hours. The pH-spectrums in 24 hours and 25 parameters were precisely calculated by the computer afterwards. Gastroesophageal refluxes in these asymptomatic infants were proved to be more frequent than previous reports. The data analysis with this system was shown to be very quick, precise and flexible, that means any newly desired parameters could be calculated easily. This system was considered to be very useful in performing the continuous esophageal pH monitoring and analysing the results.
