Figure 3: Radial artery applanation tonometry recording. The upper long panel shows the radial pressure waveform above the derived central pressure waveform. The upper right panel shows the overlaid radial waveforms, including the operator index, and the middle panel shows the quality control indices. The bottom left panel demonstrates a magnified radial arterial waveform. Systolic and diastolic pressures are 145/92 mmHg. The bottom right panel provides a magnified derived central pressure waveform. Central pressure is 137/93 mmHg.
