Ventricular tachycardia treatment

The frequency of arrhythmias from the main chambers of the heart is increasing due to rising life expectancy and better drug therapies - especially in patients after myocardial infarction and severely impaired pump function. If drug therapy fails, catheter ablation is used.


In young patients without structural cardiac changes, catheter ablation is increasingly used primarily because they do not want to take drugs for life or because they are associated with side effects. Catheter ablation of ventricular tachycardia is predominantly performed endovascularly (“from the inside”), but may also be necessary epicardially. In this case, the pericardium is punctured from the outside under the sternum, and the catheters are navigated inside the pericardium.

Das 3-dimensionale Mapping ist mit dem CT des linken Ventrikels und linken Vorhofs überlagert (CARTO merge). Die roten und grün-blauen Areale stellen die Narbe dar, aus der die Kammertachykardien kommen. Rot/rosa sind die Verödungs (Ablations)punkte markiert.
