1. A method for mapping and ablation of anomalous conduction pathways associated with a left atrium of a heart comprising the steps of:

  • (a) introducing into the left atrium of the heart a precurved, guiding introducer, wherein said introducer contains a lumen passing therethrough, a proximal end and a distal end;

    (b) introducing into the lumen of the precurved, guiding introducer a catheter for mapping and ablation of anomalous conduction pathways within the left side of the heart, wherein said catheter has one or more electrodes located at or near a distal tip of the catheter; and

    (c) extending said distal tip of the catheter through the lumen of the guiding introducer and beyond the distal tip of the guiding introducer to allow the electrodes of the catheter to map and ablate one or more anomalous conduction pathways within the left side of the heart.
