Interpretation of ECG

What is an Electrocardiogram?

An electrocardiogram is referred to as ECG. It provides a graphic representation of the electrical activity of the heart during a cardiac cycle, allowing us to visualize any anomalies and assess the heart’s functionality. Three electrical leads, one to each wrist and the left ankle, are inserted into the patient to create a conventional ECG graph, which continuously tracks the heart’s activity. Passing through our hearts, the human heart creates an electrical impulse that it then produces on its own....

History

The research of cardiac disorders was transformed 120 years ago with the invention of electrocardiography equipment. Using a mercury capillary electrometer, Augustus Waller made the first attempts to record heartbeats in 1887. The father of cardiac electrocardiography and its founder is regarded to be Willem Einthoven. To record an accurate portrayal of the ECG, he began his research using a mercury capillary electrometer and analytically reduced its distortion. With the addition of a string galvanometer that he created; he further altered the ECG recordings....

Electrocardiograph Process

The ECG test is painless and relatively easy to do. It examines the electrical changes that occur in a person’s heart during each cardiac cycle, including depolarization and repolarization. The actions that must be taken to do an ECG test are as follows: First, several tiny, adhesive electrodes are placed on the patient’s arms, legs, and chest. These electrodes are then wired to the ECG equipment to record the minute variations in the heart’s electrical activity throughout each cardiac cycle....

Electrodes and Leads

The ability to record electrical currents is made possible via electrodes, which are conductive pads fastened to the skin. By examining numerous electrodes, an ECG lead—a graphical representation of the electrical activity of the heart—is produced. In other words, the electrical currents detected by various electrodes are analyzed to determine the value of each ECG lead. The 12-lead ECG, often known as a conventional ECG, is created by utilizing 10 electrodes and is known as a 10-lead ECG. The limb leads and chest leads make up the two sets of ECG leads that make up these 12 leads....

Electrocardiograph Importance

Diagnosing cardiac arrhythmias (abnormal heartbeats) and identifying coronary artery disorders so that treatment can be started right once. It is used to check on individuals with heart conditions such as diabetes, high blood pressure, or high cholesterol. It is also capable of identifying myocardial infarctions that have already occurred. It can be used to keep an eye on any medication’s side effects. It can be used to examine the functionality of mechanical implants made into a patient’s heart. It can be used to identify non-cardiac illnesses including hypothermia or pulmonary embolism....

ECG’s Uses in Medicine

The main goal of electrocardiography is to gather data regarding the electrical impulses of the heart. This means that it may be able to identify symptoms of earlier heart attacks or even any undiagnosed cardiac ailment. The medical applications of such data are particularly beneficial and provide a greater understanding of illnesses like:...

Why is an ECG performed?

If you have any blocked or narrowed arteries in your heart (coronary artery disease), it can be used to determine or detect arrhythmias, which can cause chest pain or a heart attack. To determine whether you’ve already experienced a heart attack or not. To check to see whether the medications are having any negative impacts on our biological systems....

Diagnosed by ECG

The following are a few of the numerous heart conditions that an ECG can identify:Prior heart attacks damage to the heart, such as when one of the heart’s arteries is blocked (coronary occlusion), abnormal position of the heart, abnormal rhythm (arrhythmia) – rapid, slow, or irregular heartbeats, abnormal size of the heart, disturbances of the heart’s conducting system, abnormal rhythm (arrhythmia) – pericarditis or myocarditis, abnormal position of the heart, heart inflammation....
