Localization of the Origin of Ventricular Arrhtyhmias: Comparison of ECG Morphology and Localization Based on ECG Algorithms to Multichannel Magnetocardiography
Multichannel magnetocardiography in combination with magnetic resonance imaging permits the reliable localization of ventricular arrhythmias and assignment to anatomical structures . Especially prior to interventional treatment of ventricular arrhythmias, the localization of the arrhythmogenic substrate is important. Some parameters of the surface electrocardiogram can suggest the site of origin of arrhythmias. Additionally, algorithms have been published that permit the assignment of the origin of ventricular arrhythmias to segments of the left or right ventricle based on the morphology of the beats in the 12-lead surface ECG [2, 3, 4].
