Since more than 100 years, 12-lead
electrocardiography (ECG) is the standard-of-care tool, which involves
measuring electrical potentials from limited sites on the body surface to
diagnose cardiac disorder, its possible mechanism and the likely site of
origin. Several decades of research has led to the development of a 252-lead-ECG
and CT-scan based, three dimensional, electro-imaging modality to
non-invasively map abnormal cardiac rhythms including fibrillation. These maps
provide guidance towards ablative therapy and thereby help advance the management
of complex heart rhythm disorders. Here, we describe the clinical experience
obtained using non-invasive technique in mapping the electrical disorder and guide
the catheter ablation of atrial arrhythmias (premature atrial beat, atrial
tachycardia, atrial fibrillation), ventricular arrhythmias (premature
ventricular beats) and ventricular pre-excitation (Wolff-Parkinson-White syndrome).
