Correlation between Echo Doppler and Radial Artery Tonometer for Optimal Pacemaker Settings. Correlation between optimal AVD determined by radial artery tonometry and by echo Doppler (left panel) and between optimal VVD determined by radial artery tonometry and by echo Doppler (right panel). In 21 patients optimal VVD was 0 ms by both echo Doppler method and by applanation tonometry. Hence the dot at point 0 represents 21 patients instead of 1 patient. Similarly more than 1 patient (as shown in Table 2) who have identical VVD and AVD by echo and tonomtery are shown by a single data point.
