Assessment of endocardial activation using filtered
catheter-recorded electrograms has become a standard
clinical technique. This study aims to assess factors affecting
the accuracy of this process.
The simulation study confirmed the ability of catheterbased
signals to assess relative (“early vs. late”) timing
of ventricular activation. However, absolute errors
were high, amounting to 10% of the activation interval.
Computer-based investigations provide insight into how
relevant parameters (catheter size and angle, filtering) affect
accuracy. This may allow for further improvement of
catheter-based techniques.Assessment of endocardial activation using filtered
