Atrial arrhythmias--the dominating cardiac problem in three patients with HLA B27 associated rheumatic disorders.
Three young patients with atrial arrhythmias as the probable consequence of an HLA B27 associated inflammatory disease process are described. They are presented as an expansion of the spectrum of cardiac manifestations that can be seen in patients with HLA B27 associated rheumatic disorders, and as possible evidence of myocardial involvement of this disease process.
