Evaluation of the reproducibility and accuracy of ambulatory blood pressure monitoring using the Takeda TM-2420 automated blood pressure monitor


The reproducibility of ambulatory blood pressure measurements was assessed in eight normotensive subjects who underwent three separate days of recording, using Takeda Medical TM-2420 (TM-2420) blood pressure monitors. The coefficients of variation of mean 24 hour systolic and diastolic blood pressure were 2.1% and 2.8% respectively. The corresponding values for systolic and diastolic blood pressure variability, were 19% and 14% respectively. Measurement intervals of greater than 30 minutes significantly reduced the reproducibility of mean day interval systolic measurements. The bias of the TM-2420 systolic and diastolic blood pressure measurements compared to standard sphygmomanometer measurement were 0 +/- 7 mmHg and 1 +/- 6 mmHg respectively. Ambulatory blood pressure monitoring provides reproducible estimates of mean systolic and diastolic blood pressure, however, blood pressure variability is poorly reproducible.
