(RF)
If a tachyarrhythmia due to a specific conduction sheet or ectopic Automatiefokus, these webs or foci can (300-750 MHz) are destroyed by ablation electrode catheter with a low voltage and high frequency energy. With the aid of the current, the affected area is heated in a diameter of <1 cm and a depth of up to 1 cm and destroyed. Before the current output paths or foci must be accurately located during an electrophysiological examination.
The need to treat an arrhythmia depends on the symptoms and the risks inherent in this arrhythmia in itself. The therapy is based on the reasons behind any particular arrhythmia. If necessary, a direct antiarrhythmic therapy with anti-arrhythmic drugs, cardioversion, defibrillation, implantable cardioverter-defibrillators (ICDs), pacemaker (and a special form of “pacing”, cardiac resynchronization therapy), or a combination of these forms of treatment may be necessary.

Before the current output paths or foci must be accurately located during an electrophysiological examination. RF ablation in> 90% of cases of supraventricular reentrant tachycardia (via the atrioventricular (AV) node, or accessory pathway), (for atrial foci of atrial tachycardia or atrial flutter, focal idiopathic ventricular tachycardia VT – right ventricular outflow tract, linksseptal or bundle branch block reentrant VT) successful. Atrial fibrillation (AF) is often generated or from an arrhythmogenic focus in the pulmonary veins maintained thereof. This focus can be electrically isolated by ablation at the junction of the pulmonary vein to the left atrium or left atrium. Alternatively, an AV node ablation can be carried out by implantation of a permanent pacemaker in patients with refractory and VHF high ventricular rates. RF ablation is successful in some cases in patients with medikamentenrefraktären VT and especially in the presence of ischemic heart disease. RF ablation is a safe procedure, the mortality rate is <1/2000 cases. Complications include damage to the heart valves, stenosis or occlusion of the pulmonary veins (when used to treat atrial fibrillation), stroke, or other emboli, heart perforation tamponade (1%), and unintended AV nodal ablation.
