    ECG Machine是记录记录电活动的过程在一段时间内使用电极placed on the skin. These electrodes detect the tiny electrical changes on the skin that arise from the心muscle电生理学模式去极化repolarizing在每个过程中心beat. It is a very commonly performedcardiology测试。

    在常规的12铅ECG中,将十个电极放在患者的肢体和胸部表面上。心脏的整体大小电势然后从十二个不同角度(“铅”)测量,并在一段时间内(通常十秒钟)记录。这样,在整个心脏周期中,每一刻都会捕获心脏电去极化的总体和方向。[4]电压与此产生的时间的图无创医疗程序是electrocardiogram.

    During each heartbeat, a healthy heart has an orderly progression of depolarization that starts with起搏器细胞在里面Sinotrial节点, spreads out through the中庭, passes through theatrioventricular nodedown into thebundle of His和into thePurkinje fibers,向左散开ventricles. This orderly pattern of depolarization gives rise to the characteristic ECG tracing. To the trained clinician, an ECG conveys a large amount of information about the structure of the heart and the function of its electrical conduction system.[5]Among other things, an ECG can be used to measure the rate and rhythm of heartbeats, the size and position of the心chambers,对心脏肌肉细胞或传导系统的任何损害,心脏药物的影响以及植入的功能
