Two groups of leads are used to record an ECG: Limb or extremity leads. The three bipolar leads (I, II and III) measure the difference in potential between electrodes at two extremities, and the three unipolar leads (aVR, aVL and aVF) measure the cardiac voltage at one site relative to the central terminal.

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. Since ECG lead signals reflect activity in different parts of the heart because of their position, they are said to 'look' at different aspects of the heart: • sll, sill and aVF look at the inferior surface of the heart • si and aVL are orientated towards the superior left lateral wall A 12-lead ECG consists of three bipolar limb leads (I, II, and III), the unipolar limb leads (AVR, AVL, and AVF), and six unipolar chest leads, also called precordial or V leads, (,,,,, and). Limb leads: I, II, III, IV, V, and VI Lead IV also called AVR Lead V also called AVL In a 12-lead ECG, all leads except the limb leads are assumed to be unipolar (aVR, aVL, aVF, V 1, V 2, V 3, V 4, V 5, and V 6).

• aVF – Left Foot • Unipolar – Only one Pos(+) pole and a reference point in the center of the heart • Augmented – Voltage must be amplified by 1.5 fold • Same electrode placement as Limb Leads

To minimize electrode problems, be sure to use the proper type of electrode. Check the expiration date on any pregelled electrode before using it.

EKG-tolkning 2019-01-30 Introduktion EKG kan tolkas med olika utförlighet beroende på vad som är kliniskt relevant i situationen. Vid specialisttentamen förväntas: • basal EKG-tolkning vid fall som fokuserar på det initiala omhändertagandet • detaljerad EKG-tolkning vid momentet i deltentamen 1 som fokuserar specifikt på EKG-tolkning.

AVFs differ from arteriovenous malformations (AVMs) in that AVMs are found within the tissue of the brain or spinal cord, but AVFs are found in the coverings of the 24 Jun 2019 The combination of these sensors and contact points yield the six classic frontal leads of a full 12-lead ECG: leads I, II, III, aVL, aVR, and aVF.
