Abstract:Background
Subtypes of atrial fibrillation (AF) can differ, and exact mechanisms in which patients benefit from the pulmonary vein isolation (PVI) remain not fully understood. During PVI, vagal innervation of the heart may also be affected. Thus, non-invasive methods of intraprocedural assessment of such PVI impact are sought.
Methods
From 1-minute ECG recordings performed before and after PVI, we investigated short-term deceleration capacity (ST-DC) and s… Show more
