WebAug 31, 2024 · Morton et al. performed right atrial mapping in patients with atrial septal defect (ASD) before and late after surgical closure. 17 Electroanatomic maps of the RA demonstrated the presence of atrial conduction abnormalities, both generally and at the crista terminalis, sinus node dysfunction and atrial dilation, when compared to controls. WebWhat happens during atrial tachycardia? A normal heartbeat begins with an electrical impulse from the sinus node, a single point in the heart's right atrium (right upper chamber). During atrial tachycardia, an electrical impulse outside the sinus node fires repeatedly, often due to a short circuit — a circular electrical pathway.
