The ECG records the electric activity of the heart. You can precisely see how the electric stimulation of the heart is spread out from the SA node. The procedure implies that 6 electrodes are glued on to the surface of the breast and an other electrode is attached to each joint of the hands and feet. The electrodes measure the subtle activity of the heart.
From the recorded data conclusions can be drawn about cardiac arrhythmias and disturbances within electrical connections. These can have several causes. (e.g. after a heart attack, the electrical activity of the heart can change. It is possible to locate if possibly additional beats are coming from the atrium or the ventricle). I will show you all results, discuss these carefully with you and propose a suitable therapy if that is the case. You should know that usually, cardiac arrhythmias and many other irregularities don’t require treatment.
