Noninvasive Electroanatomic Mapping of Human Ventricular Arrhythmias with Electrocardiographic Imaging
Key result
Noninvasive electrocardiographic imaging (ECGI) successfully mapped human ventricular tachycardia activation sequences, identifying initiation sites and continuation pathways in individual patients.
Why the study?
Does electrocardiographic imaging (ECGI) allow for noninvasive mapping of ventricular tachycardia activation sequences and origins in humans?
Population
Humans with ventricular arrhythmias (ventricular tachycardia)

Cite This Study
Wang et al. (2011) conducted an observational in Ventricular arrhythmias. Electrocardiographic imaging (ECGI) vs. 12-lead electrocardiogram and invasive catheter mapping was evaluated on Mapping of VT activation sequence and identification of VT origin. Noninvasive electrocardiographic imaging (ECGI) successfully mapped human ventricular tachycardia activation sequences, identifying initiation sites and continuation pathways in individual patients.
