Atrial fibrillation was associated with decreased CAV1 in right and left atria (p = 0.03); Loss of CAV1 leads to cSrc tyrosine kinase activation, gap junction remodeling, and ventricular arrhythmia, slowing left ventricular conduction velocity, and increasing ventricular arrhythmia inducibility (32). This evidence concerns the gene CAV1 and atrial fibrillation.
