High-density EA mapping
Focal arrhythmia mapping can be challenging due to unstability of foci and/orsensibility to bumping with ablation catheter
Reentrant circuits are challenging to map for significant scar with fractionated andmulticomponent electrograms, limiting local time annotation;
Entrainment and PPI mapping techniques may be difficult to perform and interpretdue to high output pacing, lack of capture in low voltage area andinterruption/degeneration of AT;
Reliable CFAE mapping with the ablation catheter is time consuming;
Multipolar catheters may be increase clinical outcome for complex tachycardiaprocedure with respect to linear catheter (standard).
High-density mapping allows rapid assessment of:
- Focal and Macroreentrant Atrial and Ventricular Tachycardia- Complex Fractionated Atrial Electrical

Multipolar cathetersMultipolar catheters create high-density EA maps
Advantages
Higher mapping resolution (area of low voltage, channels etc.)
Usefull for unsustained tachycardia
Decreasing fluoro and mapping time
Smaller electrodes identify better endocardiac substrate with accurate time annotation
Pacing with capture at lower output because of increased electric density

How I can map .....
CONFIDENSE™ Mapping Module automate the mapping and validation processes
Cycle Length -> Only acquiring points with a consistent cycle length (CL)
Force -> Ensuring the catheter is in contact at the time of point collection
Catheter stability -> Acquiring points when the catheter location is stable
- LAT stability- Position stability
Density -> Minimises acquisition of points when the catheter is not being moved
