Assessing contact of the catheter tip with the endocardial wall remains challenging during MR-guided electroanatomic voltage mapping (EAVM) of the heart. In this study we investigated whether the synchronicity of catheter motion with the beating heart can serve as an indicator of catheter-endocardium contact. The results from this study show that that synchronicity could potentially provide an indirect measure of endocardial contact and could serve a metric by which quality of EAVM data can be evaluated.
