Atrial paced activation sequence mapping is reproducible and accurate. This study found it is relatively independent of pacing parameters, supporting its clinical use.

Area of Science:

  • Electrophysiology
  • Cardiac Mapping

Background:

  • Atrial paced activation sequence mapping shows promise but lacks systematic evaluation.
  • Key parameters like spatial resolution, reproducibility, and pacing influences require detailed study.

Purpose of the Study:

  • To systematically assess the spatial resolution, reproducibility, and impact of pacing parameters on atrial paced activation sequence mapping.
  • To validate the accuracy and reliability of this mapping technique.

Main Methods:

  • Utilized a 24-pole catheter in 15 patients, pacing at varied sites, cycle lengths (300/500 ms), and outputs (2x/10x threshold).
  • Measured activation time (AT) between adjacent dipoles.
  • Assessed spatial resolution by pacing from each dipole of a 20-pole catheter (1-3-1 mm interelectrode distance) in 10 patients.

Main Results:

  • Activation time (AT) was largely unaffected by cycle length changes.
  • Increased pacing output minimally affected AT (-2 ms maximum at RA).
  • High intraobserver (-2 to 3 ms) and interobserver (-3 to 3 ms) agreement for AT measurements.
  • Demonstrated spatial resolution of approximately 10 ms per 6 mm displacement.

Conclusions:

  • Atrial paced activation sequence analysis is a reproducible and accurate mapping method.
  • The technique's results are relatively independent of pacing parameters, enhancing its clinical utility.
