[Use of spreadsheet for statistical and graphical processing of records from the ambulatory blood pressure monitor Spacelabs 90207].
The introduction of portable devices for non-invasive ambulatory blood-pressure measurement is recognized as an advance in the study of human arterial hypertension, allowing a significant improvement in the selection of hypertensive patients as well as in the analysis of the effects of antihypertensive drugs during clinical trials. The Spacelabs 90207 is a recent example of this kind of apparatus, possessing high levels of portability and being highly classified in validation studies. Nevertheless, the software of this apparatus (like other similar devices) has severe limitations in what concerns the calculation of the area under the curve of blood pressure during the time of measurement, as well as in the possibility of grouping several records in a database for easy statistic and graphic analysis of different groups of records. In order to overcome these difficulties, the authors describe the development of a group of programs, using Microsoft Excel v3.0 spreadsheets and macros, that allow a direct import of individual files from the Spacelabs software to a spreadsheet and its further processing in three phases. These three phases, which we designated by "conversion", "export to database" and "statistic and graphic analysis", will permit an easy and fast statistic and graphic analysis of selected groups of records.
