Evaluation of acute effect by high-density grid-mapping
catheter
The acute effect of EIVOM was evaluated in the consecutive 20 patients
of the EIVOM/RF group in advance of left pulmonary vein isolation (PVI).
A high-density grid-mapping catheter (AdvisorTM HD
grid-mapping catheter; Abbott) was used to create the voltage map
before, just after, and one hour after EIVOM under 10 V of pacing from
the proximal CS site following a cardioversion.
AdvisorTM HD grid-mapping catheter was used to obtain
a bipolar electrogram. A low-voltage area (LVA) of the left atrium was
set at <0.50 mV. It was measured by two independent observers
(excluding the authors).
