Electrocardiographic imaging has been shown to be effective in the diagnosis of cardiac arrhythmias by further expanding the limits of the classic 12-lead ECG. The studies discussed in this review support ECGi as an effective non-invasive mapping tool which can assist in arrhythmic activation assessment and accurately locate their origins and conduction paths. Moreover, ECGi can not only localize atrial and ventricular arrhythmias but also distinguish whether they are focal or re-entrant, and whether they originate in the left or right atrium/ventricle. Electrocardiographic imaging can provide the healthcare professional with ample information that can help with the therapeutic approach, all non-invasively. Electrocardiographic imaging findings can also be combined with invasive procedures, such as ablation, resulting in higher treatment success rates. In future, as current limitations are overcome, ECGi will become more accessible and its potential further explored as a diagnosis enhancement.
