Ectopic activity induced by elevated atrial pressure in rabbit pulmonary vein in vitro

Atrial fibrillation ( AF ) is a common tachyarrhythmia and may cause serious complications, such as stroke. When atrial pressure was elevated, the effect refraction period (ERP) was shortened and the conductivity in atria was slowed and the heterogeneity of different parts of atria was increased. Th...

Zusammenfassung:	Atrial fibrillation ( AF ) is a common tachyarrhythmia and may cause serious complications, such as stroke. When atrial pressure was elevated, the effect refraction period (ERP) was shortened and the conductivity in atria was slowed and the heterogeneity of different parts of atria was increased. These changes facilitate the occurrence and maintenance of AF.
