Interventional Electrophysiology
Catheter ablation and electrophysiological study

• Atrial fibrillation (AF)
• Atrial tachycardia (AT) and atrial flutter (AFL)
• Paroxysmal supraventricular tachycardia (PSVT)
• Wolff-Parkinson-White (WPW) syndrome
• Ventricular tachycardia (VT): idiopathic, ischemic and non-ischemic cardiomyopathy

Device therapy
