A34-year-old man presented for evaluation of palpitations. Eight years earlier, he had undergone orthotopic heart transplantation for nonischemic cardiomyopathy. During the electrophysiology study, atrial tachycardia (cycle length, 220 ms) originating in the recipient atrium was present at baseline. Atrioatrial conduction from the recipient atrium to donor atrium was present with 2:1 conduction...

The embryonic vertebrate heart is composed of two major chambers, a ventricle and an atrium, each of which has a characteristic size, shape and functional capacity that contributes to efficient circulation. Chamber-specific gene expression programs are likely to regulate key aspects of chamber formation. Here, we demonstrate that epigenetic factors also have a significant influence on chamber m...

The distribution of these abnormal atrial electrograms within the right atrium and the way it is related to the likelihood that patients with sick sinus syndrome will develop paroxysmal atrial fibrillation was studi...
