How do specific ionic current gradients affect the left-to-right dominant frequency gradient during paroxysmal atrial fibrillation?
In-silico modeling demonstrates that IKACh and IK1 gradients are necessary to induce a left-to-right dominant frequency gradient during paroxysmal atrial fibrillation, informing potential atrial-selective therapies.
Palacio et al. (2019) studied Paroxysmal atrial fibrillation. Ionic current gradients (I KACh and I K1) was evaluated on Left-to-right dominant frequency gradient. In a 3D human atrial model, either or both I KACh and I K1 gradients were necessary to induce a left-to-right dominant frequency gradient during paroxysmal atrial fibrillation.
