Why the study?
Do right atrial monophasic action potentials and wavelength indices differ between patients with paroxysmal atrial fibrillation and controls?
Do right atrial monophasic action potentials and wavelength indices differ between patients with paroxysmal atrial fibrillation and controls?
Patients with paroxysmal atrial fibrillation exhibit shortened minimal action potential duration and increased dispersion of refractoriness, suggesting smaller wavelengths may contribute to AF genesis.

Shortened MAPD90 may indicate arrhythmogenic substrate in PAF; hypothesis-generating and requires prospective validation.
Sekiya et al. (2001) studied this question.
