title: Surgical treatment of tachyarrhythmias.
abstract: Tachyarrhythmia surgery should be divided into two separate groups: supraventricular and ventricular. Supraventricular tachyarrhythmias (SVT): The first surgical cure of the Wolff-Parkinson-White syndrome (WPW) in 1968 led to a better understanding of the pathophysiology and anatomy of this syndrome. WPW should now be classified by its anatomical location as defined by the preoperative and intraoperative mapping. At present, there are two surgical approaches for WPW, endocardial or epicardial. Improvement of the surgical results has broadened the indications for surgery of WPW, making it the most commonly performed operation for SVT. Surgical treatment is briefly discussed for AV nodal reentrant tachycardia, ectopic (focal) atrial tachycardia, atrial flutter, and atrial fibrillation. Ventricular tachyarrhythmias (VT): Different types of direct operations have been applied to the treatment of VT in ischemic heart disease. Because of the fairly high mortality and recurrence rate of these major operations in patients with poor ventricular function, there is now a marked increase in the use of implantable cardioverter-defibrillators as an indirect surgical approach.
