...; however, the ICC values and the analysis of the consistency of classification between repeated tests indicate that HRV measurements fulfil the criteria required to be used for diagnostic or classification purposes. All tests were performed in a quiet and dimmed room, at a comfortable temperature...

... sympathetic activity, their repeatability must be evaluated. 2. Intra-observer repeatability was studied by analysing changes in the LF components (expressed as absolute or normalized units) of cardiovascular variability and in the LF/HF ratio during sympathetic activation induced by nitroglycerin infusion...

... studies is an evaluation of their repeatability and spontaneous variation with time. 2. Repeatability of transcranial Doppler measurements of mean blood flow velocity and resistance index was investigated in healthy subjects by calculation of the repeatability coefficient as defined by the British...

... to assess immediate repeatability using increased 99m Tc activity (92 MBq). 3. Intrapulmonary aerosol deposition was measured with a γ-camera and was corrected for tissue attenuation and geometric distribution by using two different methods. 4. Estimated mean pulmonary deposition was 4.3% of the nebulizer...
