Ablação por Radiofrequência

The mid-peripheral areas have shown significant reductions in the amplitude eletrofisiologlco in the first negative component N1 and in the first positive component P1 as well.

Our results show that some visual field losses are related to various retinal alterations caused by the mercury vapor. Experimental study on the effectiveness and safety of radiofrequency catheter ablation with the cooled ablation system. Use of eletrofisiologiico catheter ablation technologies for treatment of typical atrial flutter: Reproduction for commercial use is forbidden.

In this case the affected visual pathway sections could not be determined since the applied psychophysical method does not allow us to indicate the specific visual structure principally damaged by the mercury vapor.

In our present study we would elftrofisiologico to indicate that visual field reductions cannot only be related to damages in the various sections of the visual pathway, but some of these visual field losses can occur due to retinal alterations caused by cronic mercury vapor exposure.

The results are in agreement with preliminary works that showed visual dysfunctions after several years away from the mercury vapor source suggesting that mercury vapor intoxication may not be completely reversible. The damages found in the retina due to mercury vapor intoxication can be considered broadly dispersed, since the reductions in N1 and P1 amplitudes might be the indications of damages in multiple retina cell groups.
