Attacks of the arrhythmia are triggered by ectopic activity originating mostly from the pulmonary veins. Left atrial myocardium frequently extends onto pulmonary veins (so called myocardial sleeves). The myocardial%22sleeves%22 will be histologically examined for the presence, quantity, and character of isolated atrial amyloid - one of the %22senile%22 amyloids. A hypothesis is put forward that amyloidosis of pulmonary veins may play a role in pathogenesis of atrial fibrillation."@en . . . "0"^^ . "2006-06-23+02:00"^^ . .
