Lead II, aVF and III are calledinferior limb leadsbecause they primarily observe the inferior wall of the left ventricle (Figure 18, coordinate system in upper panel). Lead aVL, I and –aVR are calledlateral limb leads, because they primarily observe the lateral wall of the left ventricle. ...
The 12 ECG leads are described in Chapter 3. Normal and abnormal ECG patterns are discussed in subsequent chapters. View chapterExplore book Screening for heart problems in young athletes Yogen Singh, in Paediatrics and Child Health, 2018 Utility of the 12-lead ECG While based on Italian experie...
Leads I and aVL are called ___, because they monitor the left lateral side of the heart. Leads II, III, and aVF view the lower surfaces of the heart and are called the ___. Which of the following is NOT a normal QRS measurement? A) 0.20 B) 0.08 C) 0.06 D) 0...

Dominant R wave in Leads V1 - V3.This is because of the relative large size of the right ventricle. There may be an rSR’ pattern, with narrow QRS, in V1. This is called incomplete right bundle branch block. Right bundle branch block has an rSR’ pattern with awideQRS complex. ...
The limb leads record the ECG in the coronal plane, and so can be used to determine the electrical axis (which is usually measured only in the coronal plane). The limb leads are called leads I, II, III, AVR, AVL and AVF. Figure 2 shows the rela...

These leads measure the elec- trical activity in the transverse plane. Each lead measures the potential differ- ence between an electrode placed on the torso, and Wilson's Central Terminal (Figs. 17.2, 17.3 and 17.4). Expert clinicians are able to use different leads to more effectively ...
In order to extract the internal and inter-lead features of the 12-lead ECG at the same time, we perform two-dimensional processing on the 12-lead ECG. Specifically, the leadsa∈RL×1are spliced together to form a matrixA∈RL×12, whereLis the length of leads. As shown in Fig.1, ...
