ABSTRACT:
Apparatus for curative ablation are provided to achieve the inactivation or destruction of fibrillar myocardium of the so-called AF nests. In addition, fibrillar myocardium may be identified and mapped by spectral analysis and phase study of the tissue during sinus rhythm. The procedure may be performed by transseptal puncture using only one catheter for ablation and mapping. The methods may be used to localize the application targets even during an arrhythmia.
