Cases with concurrent ablation of atrial flutter, atrial fibrillation, and ventricular arrhythmias were excluded.

Elderly patients were more likely to have underlying structural heart disease and\/or ischemic heart disease, more likely to have AVNRT and less likely to have AVRT (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

The use of stereotaxis, intracardiac echocardiography, and electroanatomical mapping did not differ significantly.
