Conclusions Because the majority of cardiac arrhythmias in individuals coming following EA may be detected by an ECG on admission, regular ECG monitoring appears to be unnecessary. However, given the potential severity of some of these conditions, it is recommended that individuals who have experienced an electric shock receive immediate care from an experienced electrocardiologist.
In intensive care units, ECG is often utilized for continuous monitoring of the patient's heart rate and the identification of potentially deadly cardiac irregularities such as arrhythmias, but it may also be used for diagnostic purposes (Gandhi & Lewis 2016). The ICU electrocardiogram (ECG) is a vital piece of equipment that plays an important role in identifying changes within the body that might indicate a problem requiring attention. The ICU electrocardiograph records the electrical activity of the heart over time. It does this by measuring the voltage across the skin surface, which reflects the change in blood volume within the heart and lungs. These electrodes are attached to the patient's chest or limbs to obtain reliable information about the heart's function.
The ICU electrocardiogram provides essential information about the status of the heart that would otherwise not be apparent from clinical examination alone. It can detect changes early on that might not be visible to the eye, such as ventricular fibrillation (VF), and it can help determine the best course of treatment for patients. For example, the ICU electrocardiogram can help guide cardiopulmonary resuscitation (CPR) efforts by indicating when there is insufficient blood flow to the brain to permit consciousness. Further, it can help identify patients at risk for sudden death due to certain disorders such as myocardial infarction or heart failure.
An ECG can aid in the detection of
An electrocardiogram (ECG or EKG) can identify irregularities in your heart's rhythm as well as specific patterns that indicate areas of the heart may be receiving insufficient blood flow. The ECG can also tell you whether you're experiencing a heart attack or if you've had one in the past. In addition, an ECG can reveal any previous damage to the heart muscle due to a heart attack or other cause. It can also show abnormalities not seen on physical examination that may require further testing.
Coronary artery disease (CAD) affects the ability of the heart to pump blood to the body. Common symptoms include chest pain or discomfort, nausea, sweating, and shortness of breath. If you have any of these symptoms, call your doctor immediately.
Your doctor will perform various tests to determine the cause of your symptoms and check for signs of heart disease. These tests may include:
Echocardiography: This test uses sound waves and a computer to create images of your heart's structure and function that allow your doctor to see problems with the lining of the heart, the size of the chambers, and the presence of scar tissue following a previous heart attack.
Electrocardiography (ECG or EKG): This test records the electrical activity of your heart to detect changes associated with CAD.
An ECG may also be recommended by a doctor for persons who are experiencing symptoms such as chest discomfort, shortness of breath, dizziness, fainting, or rapid or irregular heartbeats. The ECG is a non-invasive, safe treatment with no known dangers. It is important to note that excessive heat or cold can cause abnormalities in the heart's electrical system that can be interpreted as damage; therefore, patients should avoid overexertion and exposure to extreme temperatures during testing.
An ECG measures the voltage across the skin's surface, from one arm to the other, or from the front to the back, in order to detect changes that may occur due to disease or injury. These changes can indicate problems such as heart attack, heart failure, abnormal rhythms, myocardial infarction (MI), and stroke.
The ECG machine produces small electrodes that are attached to the skin's surface at specific locations. These locations are chosen so that different areas of the body will produce different results. For example, placing the electrodes on the upper body will show us how the heart functions, while placing them on the lower body will show us how it malfunctions. Only certain parts of the body are tested, never the whole body. Test results are displayed immediately after each other in separate graphs or charts. A physician reviews these results with you to determine if there is any reason why your heart should not function normally.
