Abstract

Echocardiography is a non-invasive, safe means of assessing intracardiac structures and their motion. In the normal motion of the mitral valve there is anterior motion noted during atrial systole. In 3 horses with atrial fibrillation the mitral valve motion had no anterior motion to correspond with atrial contractions. Quinidine returned the electrocardiogram of one horse to a sinus rhythm after which echocardiography demonstrated the reappearance of the anterior motion of the mitral valve.

摘要

超声心动图是一种评估心脏内部结构及其运动的无创、安全的手段。在二尖瓣的正常运动中，心房收缩期可观察到向前运动。在3匹患心房颤动的马中，二尖瓣运动没有与心房收缩相对应的向前运动。一匹马使用奎尼丁后心电图恢复为窦性心律，之后超声心动图显示二尖瓣向前运动再次出现。
