Description: An electrocardiogram (ECG) is a recording of the heart’s electrical activity, which can provide information about abnormal heart conditions. In the critical care unit, patients are connected to a continuous ECG monitor that can detect changes in the heart, which can influence a patient’s treatment plan. A more extensive 12 lead ECG can be performed on the patient, when the patient is experiencing certain symptoms, such as chest pain. A 12 lead ECG, along with blood tests, can lead to important medical diagnosis, such as a heart attack.
