Key Points

  • To evaluate whether catheters with smaller electrodes and closer interelectrode spacing improve electrogram mapping resolution in low-voltage, scar-related atrial substrates.
  • Assessed cardiac mapping resolution using catheters equipped with smaller electrodes and tighter interelectrode spacing across low-voltage tissue areas.

Structured PICO

Does mapping with small closely spaced electrode catheters improve mapping resolution within areas of low voltage in scar-related atrial arrhythmias?
