This chapter reviews atrial fibrillation (AF) progression and its associated mechanisms, including comorbidities and AF as contributors to atrial myopathy, and atrial myopathy as a contributing factor to AF progression. In addition, the chapter discusses the concept of comorbidities and atrial myopathy as synergistic contributors to adverse outcomes, the notion of "AF begets AF," and the consequences of AF burden if left untreated. Clinical trials evaluating outcomes with antiarrhythmic drugs (AADs) compared with placebo have demonstrated efficacy, but also reveal a possible proarrhythmic and mortality risk if AAD selection is not appropriate and patients are not correctly identified based on risk factors and comorbidities. Data from ATHENA, the first and only trial to demonstrate that an AAD (dronedarone) can reduce cardiovascular (CV) hospitalizations in people with AF, are reviewed, along with studies reporting on the use of catheter ablation versus AADs for AF rhythm control. Finally, recent data showing a reduction in major adverse outcomes if rhythm control is initiated early are summarized, including results from the EAST-AFNET 4 trial, as well as confirmatory results from several large "real-world" trials. Chapter 3 is summarized as follows.

Numerous studies have reported benefits of music listening to support learning and motor rehabilitation. In the case of handwriting, previous studies suggested that musical background improves movement speed and fluency. Whether this benefit comes from the melody or is specifically related to the rhythmic cues provided by the music remains to be established.

Background: Ventricular fibrillation (VF) is a vicious arrhythmia usually generated after removal of the aortic cross-clamp (ACC) in patients undergoing open-heart surgery, which could damage cardiomyocytes, especially in patients with left ventricular hypertrophy (LVH). Amiodarone has the prominent properties of converting VF and restoring sinus rhythm. However, few studies concentrated on the effect of amiodarone before ACC release on reducing VF in patients with LVH.

Approaches to mitigate the severity of infections and of immune responses are still needed for the treatment of cystic fibrosis (CF) even with the success of highly effective modulator therapies. Previous studies identified reduced levels of melatonin in a CF mouse model related to circadian rhythm dysregulation. Melatonin is known to have immunomodulatory properties and it was hypothesized that treatment with melatonin would improve responses to bacterial infection in CF mice.

Objective: A motor imagery (MI)-based brain-computer interface (BCI) enables users to engage with external environments by capturing and decoding electroencephalography (EEG) signals associated with the imagined movement of specific limbs. Despite significant advancements in BCI technologies over the past 40 years, a notable challenge remains: many users lack BCI proficiency, unable to produce sufficiently distinct and reliable MI brain patterns, hence leading to low classification rates in their BCIs. The objective of this study is to enhance the online performance of MI-BCIs in a personalized, biomarker-driven approach using transcranial alternating current stimulation (tACS).
