Discussion
In this study, we provide an industry-independent validation of the
accuracy of contemporary contact force ablation catheters. The main
findings of this study are:
First, the overall correlation between measured force and real force was
excellent with 𝜌𝑆𝑝𝑒𝑎𝑟𝑚𝑎𝑛 ≥0.98 for all models. Second,
within the clinical range of 10g-40g the absolute measurement errors
were low with mean errors of <3g. Third, at higher forces,
some combinations of catheter and angle can result in significant
underestimation or overestimation of the real force by more than 15g.
