The electrocardiogram (EKG or ECG), widely recognized as a crucial diagnostic instrument in contemporary medical practice, is employed to capture and document the electrical impulses generated by the heart. The names EKG and ECG are synonymous, with ‘EKG’ originating from the German term “Electrocardiograms.” The use of this non-invasive treatment holds significant importance in the identification of several cardiac ailments, encompassing arrhythmias, myocardial infarctions, and congenital heart anomalies. The heart, fundamentally, is a specialized muscular organ that has the primary purpose of circulating blood throughout the body, hence providing essential oxygen and nutrients to various tissues. This process is accomplished by a sophisticated series of contractions and relaxations, coordinated by a complicated electrical conduction system. The initiation of each heartbeat is attributed to the electrical impulse that starts from the sinoatrial (SA) node, which is situated in the right atrium. Subsequently, the aforementioned impulse propagates across the atria, inducing their contraction and facilitating the propulsion of blood into the ventricles. Following this, the electrical signal proceeds to the atrioventricular (AV) node, where a slight delay occurs, facilitating the full filling of the ventricles with blood. Subsequently, the electrical impulse propagates down the bundle of His, bifurcates into the Purkinje fibers, and initiates the contraction of the ventricles, so facilitating the circulation of blood to both the systemic and pulmonary circulatory systems. The electrocardiogram (EKG) records the electrical activities of the heart in the form of distinct waveforms, namely the P wave, the QRS complex, and the T wave. The P wave signifies the electrical depolarization of the atria, which initiates their contraction. The QRS complex reflects the electrical depolarization of the ventricles, which triggers their contraction. Lastly, the T wave corresponds to the phase during which the ventricles repolarize in preparation for the subsequent cardiac cycle.
