The pitfalls of unipolar voltage mapping of the right ventricle

Conclusion In the majority of endocardial and epicardial points the window-of-interest for unipolar voltage mapping needs to be adjusted to exclude far-field signal or ST-segment elevation/depression contributing to the automatically determined amplitude. Unadjusted unipolar voltage mapping underestimates low UV regions. RV-pacing generates a large unipolar far-field signal, which can obscure the local unipolar near-field signal. Accordingly, RV UV mapping during RV pacing should be used with caution. Abstract Figure. The pitfalls of UV mapping of the RV
