PALPATION OF INTRA-CARDIAC BLOOD FLOW, PRESSURE, CONTACT FORCE AND MOTOR REACTION TIME OF SUBJECTS USING A NOVEL HAPTIC FEEDBACK SYSTEM

Results: Mean tactile motor RT for two subjects measured 10 times = 185 ms (SD = 32) which was statistically significantly less than visual motor RT for historical controls; n = 93; mean = 321.8 ms (SD = 38.6); p < 0.0001 (unpaired t-test) at 95% confidence level. 14 of 14 physicians differentiat...

Summary:Results: Mean tactile motor RT for two subjects measured 10 times = 185 ms (SD = 32) which was statistically significantly less than visual motor RT for historical controls; n = 93; mean = 321.8 ms (SD = 38.6); p < 0.0001 (unpaired t-test) at 95% confidence level. 14 of 14 physicians differentiated haptic feedback from LA and PV, right from left atrial pressure, time of contact with and puncture of the septum, and changes in CF amplitude due to cardiorespiratory cycles. 11 of 14 preferred to control the gain of haptic effect.
