P-wave morphology in focal atrial tachycardia using a 3D numerical model of the heart

Abstract

Atrial arrhythmia resulting from irregularly rapid focal activity in the atria may be revealed in an altered P-wave morphology (PWM) in the ECG. A 3D computerised model of the heart was used for simulating the electrical activity of the atria measured in the 12 ECG leads during normal rhythm and during focal atrial tachycardia. This simulation was conducted for determining the focal origin of the atrial tachycardia by analysing the P-wave morphology in the simulated 12 ECG leads and compare these results to previously published clinical results.
