What is an ECG?

ECG. An ECG or electrocardiogram records the electrical activity of the heart by placing electrodes over skin. There are different types of ECG, depending upon the number of electrodes like 1-lead, 2-Lead, 6-Lead, and 12-Lead. 1-lead ECG is used for basic heart monitoring.

What are the shortcomings of ECG?

This procedure has many shortcomings like: 1 Application of single-lead electrodes to the torso to get 12-lead ECG readings takes time that can cause major ECG changes. 2 The movement of an electrode from one part to another can affect ECG readings. 3 Its precision is operator-dependent, thus raising clinician’s concerns about the accuracy and reliability of reading. 4 This setting has the potential for false‐negative test results that can lead to potentially fatal missed diagnosis.

Why is ECG important?

In terms of diagnosis, ECG measurements are most important for the initial assessment of the patient. ECG not only helps in establishing the diagnosis, but it also evaluates the changes in cardiac status from time to time. It also helps in the prediction of future events to make appropriate treatment decisions.

What are the two pillars of cardiac emergency?

In a cardiac emergency, the two pillars that facilitate the right diagnosis and treatment are; the time and accuracy of every verbal or diagnostic information. Both of these have a critical effect on the outcomes of the cardiac patient.

Participants will be able to recognize a STEMI.

What is an ECG lead?

An ECG lead is a graphical description of the electrical activity of the heart and it is created by analysing several electrodes.

How does an electrocardiograph generate an ECG lead?

Figure 16. The electrocardiograph generates an ECG lead by comparing the electrical potential difference in two points in space. In the simplest leads these two points are two electrodes (illustrated in this figure). One electrode serves as exploring electrode (positive) and the other as the reference electrode. The electrocardiograph is constructed such that an electrical current traveling towards the exploring electrode yields a positive deflection, and vice versa.

What is Mason Likar's lead system?

Mason-Likar’s lead system simply implies that the limb electrodes have been relocated to the trunk. This is used in all types of ECG monitoring (arrhythmias, ischemia etc). It is also used for exercise stress testing (as it avoids muscle disturbances from the limbs).

What is the order of the leads in the Cabrera system?

In the Cabrera system, the leads are placed in their anatomical order. The inferior limb leads (II, aVF and III) are juxtaposed, and the same goes for the lateral limb leads and the chest leads. As mentioned earlier, inverting lead aVR into –aVR improves diagnostics additionally.

What is the lateral limb lead?

Lead aVL, I and –aVR are called lateral limb leads, because they primarily observe the lateral wall of the left ventricle. Note that lead aVR differs from lead –aVR (discussed below). All six limb leads are presented in a coordinate system, which the right hand side of Figure 18 (panel A) shows.

Where are the limb leads placed?

Leads I, II, III, aVF, aVL and aVR are all derived using three electrodes, which are placed on the right arm, the left arm and the left leg. Given the electrode placements, in relation to the heart, these leads primarily detect electrical activity in the frontal plane.

What is the difference in electrical potential?

Electric potential difference is defined as a difference in electric potential between two measurement points. In electrocardiology these measurement points are the skin electrodes. Thus, the electrical potential difference is the difference in the electrical potential detected by two (or more) electrodes.

What is a 12 lead ECG?

A 12-lead ECG is much more specific as it is a diagnostic tool looking at the electrical activity of various sections of the heart simultaneously. It can allow the person reading the 12-lead ECG to identify early signs of ischemia, injury and infarction of very valuable heart muscle.

Why is it important to have a 12 lead ECG?

The objective of this report is to provide Paramedics with basic knowledgeprior to the introduction of acquiring 12-lead ECGs as part of their scope of practice.Acquisition of 12-lead ECGs will become an additional tool, along with currentassessment skills, for identifying patients suffering from an acute myocardial infarction.The importance of obtaining a 12-lead ECG is for early identification of potentialmyocardial ischemia so that the cause can be appropriately treated and, hopefully,reversed.

What is the focus point of precordial leads?

The precordial leads, like the augmented leads, are all positive and all use the neutral center of the heart as their “focus” point. We will go into the actual physical identification for locating these leads in another module, for now it will be simplest to use the following chart to identify each electrode location and the section of the heart that the lead is viewing.

Where are the leads on a 12 lead ECG?

Leads II, III and aVF are leads that have their positive electrode located at the left foot. They are contiguous leads that all look at the inferior wall of the left ventricle. Leads I and aVL are leads that have their positive electrode located on the left arm. These leads view the high lateral wall of the left ventricle.

What is anatomically contiguous lead?

Anatomically contiguous leads are two or more leads that look at adjoining areas of tissue. Determining which leads are contiguous may be confusing, but the easiest explanation is this; if the leads have the same name (for example, inferior) they are contiguous. With the chest leads, if they are consecutively numbered they are also contiguous. For example, V2 is called a septal lead and V3 an anterior lead, not the same name but they are both chest leads and numerically consecutive so, therefore, they are contiguous.

What is the difference between augmented leads and limb leads?

Augmented Leads. The augmented leads use the same lead locations as the limb leads. What gives us the difference in the view of the heart is the fact that all of the electrodes on the limbs are positive and they look towards the neutral center of the heart.

What is the lead in the heart?

The lead we are most familiar with is Lead II, which is one of the limb leads. Lead I, Lead II and Lead III combine to form a triangle around the perimeter of the heart. This triangle is frequently referred to as Einthoven’s Triangle, named in the early 1900’s after a pioneer in electrocardiography.
