Afterward, you'll be taken to a recovery area for a few hours where care providers will closely monitor you. WPW is caused when an extra electrical pathway, found between the hearts upper chambers (atria) and the hearts lower chambers (ventricles), causes a rapid heartbeat (tachycardia) For people with WPW, the extra electrical pathway is present at birth and is considered fairly rare. The use of optical fibers for laser delivery also provides an option for reflectance spectroscopy as a feedback mechanism on both contact as well as lesion progression in real time. Once you are back to your baseline state of consciousness, the electrophysiologist should visit you to explain exactly what they did during the ablation procedure, and how confident they are that the procedure was a complete success. In the catheterization lab, you will be asked to lie down on the procedure table. Techniques for modification of the left atrial substrate for AF include linear ablation and ablation of complex fractionated electrograms.
