Advances in catheter ablation for the treatment of cardiac arrhythmias

RF catheter ablation has become the nonpharmacologic treatment of choice for refractory cardiac arrhythmias. Single carefully directed RF lesions are capable of curing most supraventricular tachycardias. Recent developments in cardiac mapping and lesion formation allow for the analysis and treatment of more complex arrhythmias. Such new technology should help to expand the number of patients successfully treated with catheter ablation.
