Summary Introduction

Introduction:

The electrocardiogram (ECG) is a process through which the electrical activity of the heart is recorded on a characteristic graph paper. The heart is myogenic, that means it consists of specific cardiac muscles that can generate electrical impulses on their own. The sinoatrial nodes are the pacemakers of the heart. The ECG records the electrical activity of the heart on a graphical paper where different tracings are present. The tracings correspond to the systole, diastole and other processes in the heart. The graphical representation has a characteristic amplitude, direction, and duration of the different tracings. The standard ECG uses a 12-lead system, which are the electrodes.
