How to perform pulmonary vein isolation.

The advent of technology for the delivery of radiofrequency energy via electrode catheters, in the late 1980s, led to the perfection of techniques for the ablation of accessory pathways and classical flutter [1e4]. This has been so successful that these substrates for arrhythmia are rarely seen in the Western world. Two major arrhythmias, however, still remain to be conquereddatrial fibrillatio...

Ontology Integration: How to perform the Process
