Nurses are usually the first ones to read that “hot off the press” EKG tracing. A 12-lead EKG is considered the gold standard; however, a 4 lead EKG can also diagnose different heart conditions. ECG lead aVR, aVF and aVL (Goldberger’s leads) These leads were originally constructed by Goldberger. In these leads the exploring electrode is compared with a reference which is based on an average of the other two limb electrodes. The letter a stands for augmented, V for voltage and R is right arm, L is left arm and F is foot. All patients with MLAD lesion were identified and their ECG reviewed for TWI in lead aVL.

There is also subtle ST elevation in the high lateral leads (I and aVL); this may be easily missed. However, the presence of reciprocal ST depression in the inferior leads (III and aVF) makes the lateral ST elevation more obvious. This ECG represents the early stages of a large anterolateral infarction. ECG Interpretation Part 1: definitions, criteria, and characteristics of the normal ECG (EKG) waves, intervals, durations & rhythm. This is arguably one of the most important chapters throughout this course.

Rätt kopplat EKG – en förutsättning för rätt diagnos

Rutinmässigt används 12 avledningar, 6 bröstavledningar och 6 extremitetsavledningar i ett vilo-EKG (läs mer i texten Olika EKG-avledningar). - EKG registrerat inför arbetsprov.

ST elevation in the lateral leads (I, aVL, V5-6). Reciprocal ST depression in the inferior leads (III and aVF). ST elevation primarily localised to leads I and aVL is referred to as a high lateral STEMI. NB. Reciprocal change in the inferior leads is only seen when there is ST elevation in leads I and aVL. Figure 1. ECG changes seen in left ventricular hypertrophy (LVH) and right ventricular hypertrophy (RVH). The electrical vector of the left ventricle is enhanced in LVH, which results in large R-waves in left sided leads (V5, V6, aVL and I) and deep S-waves in right sided chest leads (V1, V2). 2021-03-24 · • si and aVL are orientated towards the superior left lateral wall • aVR and V1 face the cavity of the heart and the deflections are mainly negative in these leads • Leads V1-6 are orientated towards the anterior wall.
