心脏就像一个泵,每次搏动都将血液泵向全身,为全身的组织和器官提供氧气和营养物质。心脏的这种机械活动是受电活动控制和支配的,正常情况下,电活动来源于位于心房的窦房结,窦房结规律发出电脉冲,每分钟60～100次,向心脏各部分传导,引起心脏各部位顺序收缩(心房到心室)。房颤就是心脏的电活动不再受窦房结支配,被心房内快速、杂乱无章的电活动替代,相应心室出现快速而没有规律的收缩和舒
The heart acts like a pump, pumping blood all the way to each beat, providing oxygen and nutrients to the tissues and organs of the body. The heart of this mechanical activity is controlled and dominated by electrical activity, under normal circumstances, the electrical activity from the sinoatrial node in the atrium, the sinus node sends out an electrical pulse, 60 to 100 times per minute, to the heart of various parts of conduction , Causing all parts of the heart sequence contraction (atrial to ventricular). Atrial fibrillation is the heart’s electrical activity is no longer dominated by the sinus node, the atrium is fast, disorganized electrical activity alternative, the corresponding ventricular rapid and non-regular contraction and Shu
