Figure legends
Figure 1: A: Intra-cardiac electrocardiogram mapping of the right
atrium, right ventricle and functional tricuspid annulus. All mapping is
done during inspiration and diastole. The purple tag represents
funcitonal annulus. B-1: Endocardial electrocardiogram during successful
ablation. The atrial and ventricular activity were fused at ABL1-2, and
the atrial activity disappeared after ablation. B-2: 3D view of
funcitonal annulus and ablation success point. The red tag was the
ablation tag, the * is the success point. The functional annulus and the
ablation success point were far apart.
ARA: arterized right atrium, RV: right ventricle, FA: functional
tricuspid annulus, LAO: left anterior oblique, RAO: right anterior
oblique
Figure 2: A: 12-lead electrocardiogram during rapid wide QRS response
via accessory pathway during AF. Atrial waves were recorded at 9-10 of
the Penta ray, indicating that the valve leaflets were being mapped.
Narrow QRS conducts through the AV node, and wide QRS conducts through
the accessory pathway. B: Maximum pre-excitation pattern matching data.
The pattern of waveform acquisition was from pre-excitation to the end
of the QRS in the wide QRS waveform via accessory pathway during atrial
fibrillation. C: :Mapping of ventricular activity with maximum
pre-excitation. Narrow QRS 1 was conduction through the AV node. No
potential was acquired under waveform 1 by pattern matching. Wide QRS 2,
a potentials was not acquired because pattern matching score is unde the
correlation threshold. Wide QRS 3 was acquied a potential because
pattern was matched. To acquire potentials from the preexitation of the
wide QRS to the end of the QRS, waveforms in the range shown in the
figure were acquired.
Figure 3: A is propagation map using LAT resulted in a disordered map
and B is Ripple map (RM). A, B and C, in that order, are still images of
10msec each. They are in chronological order from 1 to 3. The map A can
be seen that the propagation does not identify the acesory pathway. The
map B was used to identify the accessory pathway during AF. The ripple
map bars show the tricuspid annulus passing through the accesory pathway
as the earliest in the timeline. The red and pink tags are ablation tag.
