Summary

This study is to investigate the correlation and to obtain the coefficient of correlation between the global and local bipolar signals (voltage maps) of the LA in sinus rhythm using a focal 4.5 mm irrigated-tip ablation catheter (in combination with microelectrodes), a ring-electrode circular mapping catheter and a microelectrode multipolar catheter in combination with the Rhythmia system.

Conditions

  • Atrial Fibrillation (AF)

Interventions

DIAGNOSTIC_TEST

multipolar mapping catheter

mapping of the left atrium will be performed in sinus rhythm using the IntellaMap Orion multipolar mapping catheter (Boston Scientific).

DIAGNOSTIC_TEST

multielectrode circular catheter

mapping of the left atrium will be performed using the multielectrode circular catheter (Lasso, spacing 2-6-2 mm, Biosense Webster)

DIAGNOSTIC_TEST

irrigated ablation catheter

mapping of the left atrium will be performed using the irrigated ablation catheter (IntellaNav Mifi OI)
