Abstract

Recording an electrocardiogram or ECG, is a procedure which is performed daily all over the United Kingdom by thousands of healthcare workers and in particular nurses (Jacobson, 2000). The way in which this procedure is performed varies from geographical location to location and occasionally even more so, between staff on the same ward (Amos, 2000). This reason stated by Amos (2000), formed the basis of my decision to choose this topic.

The recording of an ECG is often seen as a fairly mundane, routine …show more content…
However, Cowley (2002) suggests that although this may eliminate problems of interpretation and encourage prompt review of ECG’s, the basics of lead placement remain essential knowledge.
Section Two – Incorrect lead placement
According to Cowley (2002) the analysis of the twelve lead ECG is all about measurements, the height and depth of waves which are important in the diagnosis of certain conditions such as myocardial infarction or hypertrophy. Lead placement is especially important if the extent of these conditions is to be determined and treated appropriately (Jacobson, 2000). The following changes in the twelve lead ECG have been shown to occur when the electrodes are placed incorrectly on the torso; • A shift in the cardiac axis towards the right, which has clinical significance in that, patients may be seen to have ventricular hypertrophy and subsequent incorrect medical and nursing management. • R wave becomes smaller in lead I, which could result in the missed diagnosis of ventricular hypertrophy and subsequent incorrect management. • Less prominent Q waves in inferior leads, which would result in the mis-diagnosis of an established myocardial infarction and subsequent incorrect medical and nursing management.

What Is 12-Lead ECG Analysis?

The ECG provides a representation of the electrical activity of the human heart and is a very important tool for the diagnosis of disturbances of heart rate and rhythm. The ECG is derived by placing electrical leads on a patient’s chest and limbs and provided one of the first methods for automatically determining heart rate (HR) and detecting irregular rhythms of the heart. Original monitors allowed physicians and nurses the ability to watch the ECG trace on an oscilloscope. Since ECG signal measured…

values such as integrity, resilience, and empathy. Halfway through an overnight shift, my partner and I responded to an elderly patient who was complaining of generalized body aches. Considering this a basic life support patient, I downgraded that patient to my partner. At the hospital, a 12-lead ECG showed our patient was experiencing a myocardial infarction (STEMI); requiring transfer to a percutaneous coronary intervention (PIC) capable hospital. Later, I learned the patient died after arriving…

the diagnostic tests available to detect heart muscle damage are an electrocardiogram (ECG), echocardiography, cardiac MRI and various blood tests. The most often used blood markers are the creatine kinase-MB fraction and the troponin levels. Immediate treatment for suspected acute myocardial infarction includes oxygen, aspirin, and nitroglycerin. Most cases of myocardial infarction with ST elevation on ECG are treated with reperfusion therapy, such as percutaneous coronary intervention or thrombolysis…
