Validation of the mapping accuracy of a novel non-invasive epicardial and endocardial electrophysiology system.

Aims: Use of a non-invasive electrocardiographic mapping system may aid in rapid diagnosis of atrial or ventricular arrhythmias or the detection of ventricular dyssynchrony. The aim of the present study was to validate the mapping accuracy of a novel non-invasive epi- and endocardial electrophysiology system (NEEES).

Methods And Results: Patients underwent pre-procedural computed tomography or magnetic resonance imaging of the heart and torso.
