Atrial fibrillation: Neurogenic or myogenic?
Scridon A, Şerban RC, Chevalier P. Scridon A, et al. Arch Cardiovasc Dis. 2018 Jan;111(1):59-69. doi: 10.1016/j.acvd.2017.11.001. Epub 2017 Dec 8. Arch Cardiovasc Dis. 2018. PMID: 29229215 Free article. Review.
Contrary to what is often stated, autonomic imbalance is not a simple modulation factor of atrial fibrillation; both the trigger and the substrate of atrial fibrillation can be influenced by abnormal cardiac innervation. Here, we review the neurogenic theory of atrial fibr …

The U-wave: A remaining enigma of the electrocardiogram.
Kihlgren M, Almqvist C, Amankhani F, Jonasson L, Norman C, Perez M, Ebrahimi A, Gottfridsson C. Kihlgren M, et al. J Electrocardiol. 2023 Jul-Aug;79:13-20. doi: 10.1016/j.jelectrocard.2023.03.001. Epub 2023 Mar 5. J Electrocardiol. 2023. PMID: 36907158 Review.
Various pathologic conditions were found to correlate with the presence and properties of the U-wave, such as its amplitude and polarity. Abnormal U-waves can, for example, be observed in coronary artery disease with ongoing myocardial ischemia or infarction, ventri …

Irreversible electroporation ablation for atrial fibrillation.
Wojtaszczyk A, Caluori G, Pešl M, Melajova K, Stárek Z. Wojtaszczyk A, et al. J Cardiovasc Electrophysiol. 2018 Apr;29(4):643-651. doi: 10.1111/jce.13454. Epub 2018 Mar 6. J Cardiovasc Electrophysiol. 2018. PMID: 29399927 Review.
While still in its preclinical steps for what concerns interventional cardiac electrophysiology, multiple studies have shown the efficacy of this method on animal models. The observed remodeling process shows this technique as tissue specific, triggering apoptosis r …
