This randomized sham-controlled study tested low-level electromagnetic field stimulation (3.2 × 10 G at 0.89 Hz) applied around the head in patients undergoing ablation for paroxysmal atrial fibrillation. Eighteen patients completed the protocol, and LL-EMF was associated with shorter pacing-induced AF episodes after…

This pre/post study measured circulating microRNA profiles in 30 atrial fibrillation patients before and 3 months after radiofrequency ablation, comparing results with 10 healthy controls. The authors report that numerous miRNAs differed from controls at baseline and shifted after ablation, with several highlighted…

This study evaluated whether fusing delayed enhancement MRI (DE-MRI) with magnetic resonance angiography (MRA) improves visualization of radiofrequency ablation lesions after pulmonary vein isolation. Eighteen atrial fibrillation ablation patients underwent both imaging approaches, and two observers scored lesion…

This feasibility study evaluated whether delayed-enhancement MRI (DE-MRI) using commercially available tools could visualize radiofrequency ablation lesions in Japanese patients with atrial fibrillation. Of 15 scans, 3 were uninterpretable due to low image quality, and lesions were visualized in 8 of the remaining 12…

This animal study tested whether extremely low-level pulsed EMF (0.034 μG, 0.952 Hz) could suppress induced atrial fibrillation in 17 anesthetized dogs. EMF applied to cervical vagal trunks or across the chest was reported to suppress neural firing in the anterior right ganglionated plexi. The authors report that EMF…
