In patients with atrial fibrillation, significant discrepancies are likely to occur between invasive and non-invasive arterial blood pressure measurements, and the magnitude of error is reported to increase for both systolic and diastolic blood pressure. Previous studies comparing invasive and non-invasive arterial blood pressure in patients with atrial fibrillation have primarily used the Bland Altman method, which involves a simple comparison between the two measurements. Recently, an error grid analysis, a novel analytical method that incorporates the clinical risk associated with blood pressure differences, has been developed for comparing two blood pressure measurements. The aim of this study was to evaluate the differences between invasive and non-invasive arterial blood pressure in patients with atrial fibrillation using error grid analysis.

A comparison was performed between invasive arterial blood pressure and non-invasive arterial blood pressure measured using a cuff-based device. Student's t test and the Mann-Whitney U test were used for statistical comparisons, as appropriate. In addition, measurement error was evaluated using error grid analysis, with reference to a previous study. In error grid analysis, the plot is divided into zones A through E, with zone A representing the smallest error and subsequent zones (B to E) indicating progressively larger errors. According to the report by Saugel et al., if more than 90% of measurement points fall within zone A, the difference is considered clinically acceptable. To avoid interference between measurements, invasive and non-invasive arterial blood pressure were measured in different upper limbs in this study.
