英文摘要
Atrial fibrillation, the most common sustained arrhythmia, is believed to be triggered by ectopic electrical activity originating in the myocardial sleeves surrounding the pulmonary veins. In this study, we found that cardiomyocytes in rat pulmonary veins possessed morphological and electrophysiological properties different from those of atrial myocytes. We concluded that these properties play functional role in norepinephrine-induced spontaneous activity of pulmonary vein cardiomyocytes.
