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.
