心脏活动是一个心电激动与心肌机械活动的综合过程,首先产生电激动,而后在相应部位出现心肌机械运动。心电图有助于观察电活动的起源与传导从而确定心律失常的类型,而超声心动图可通过观察房室壁和瓣膜运动、心内血流频谱的变化来明确心脏机械运动的节律异常,从而确定心律失常的类型。两者从不同角度对应观察,有助于了解与判断心律失常的类型及其发生的机制。
Cardiac activity is a combined process of electrocardiographic and myocardial mechanical activity, which first produces electrical activation followed by myocardial mechanical motion at the corresponding site. ECG can help to observe the origin and conduction of electrical activity to determine the type of arrhythmia, and echocardiography by observing the atrioventricular wall and valve movement, changes in intracardiac blood flow to clear the rhythm of heart rhythm abnormalities to determine The type of arrhythmia. Corresponding observation from different angles helps to understand and judge the type of arrhythmia and its mechanism.
