Abstract 10876: New Blood Pressure Measurement Approach
Aim of the study: Comparison of 5 minutes’ beat to beat measurement of blood pressure (BP) with ambulatory , 24 hours, measurement (AM).
Material and Methods: 38 patients with hypertension were studied under strictly standardized conditions. Blood pressure at rest was measured using the task force monitor (TFM) (MedX5 program, CNSystems,Graz,Austria). For ambulatory blood pressure analysis, a commercially available system was used (Spacelabs,Co.).
Results: Mean heart rate of the measurements (BP, AM) correlated significantly between the methods (r = 0.85,p < 0.01).Mean arterial BP measured with TFM was closley related to AM results:r= 0.57 (p < 0.05). Mean differences between the two measurement was 1.9mmHg (insignificant difference). Mean systolic and diastolic blood pressure values demonstrated a significant relationsship between BP and AM: r = 0.56 (p< 0.05) for systolic and r= o.65 (p< 0.01) for diastolic blood pressure values. Mean values for systolic data differed 1.7 mmHG and for diastolic data 8.9 mmHg between BP and AM.
Conclusion: Beat to beat measurement of blood pressure during 5 minutes (i.e. 300 values or more) predicted reliably results of 24 hours measurement.Therefore, with respect to strictly standardized conditions,short-term measurement with the TFM system may replace ambulatory measurement. TFM systems are widely in use for diagnosis of syncope .This system then may simplify diagnosis of hypertension and control of therapy.
