What does AVf mean on ECG?
Unipolar Leads
| Label | Meaning of label | Position of lead on body |
|---|---|---|
| AVr | Augmented vector right | Right wrist |
| AVL | Augmented vector left | Left wrist |
| AVf | Augmented vector foot | Left foot |
Where would leads AVr AVL and AVf be placed?
Cardiology Teaching Package Well, the 2 leads situated on the right and left wrist (or shoulders), AVr and AVL respectively, and the lead situated on the left ankle (or left lower abdomen) AVf, make up a triangle, known as “Einthoven’s Triangle”. Information gathered between these leads is known as “bipolar”.
What type of leads are aVR aVL and aVF?
The augmented leads aVR, aVL, and aVF are unipolar and record the electrical difference between the right and left arms and the left foot utilizing a central negative lead (see Frontal Plane: Six Limb Leads).
How is aVF calculated?
aVF=EF – 1/2 (EL + ER) [10]. aVR+aVF+aVF=0 [12]. and introduce it in the equation [10] as follows: aVF=II+ER – 1/2(EL+ER) [14].
What does aVR look at on ECG?
The lead aVR is oriented to ‘look’ at the right upper side of the heart, and can provide specific information about the right ventricle outflow tract and basal part of the septum (10).

How is an ECG interpreted?
ECG interpretation includes an assessment of the morphology (appearance) of the waves and intervals on the ECG curve. Therefore, ECG interpretation requires a structured assessment of the waves and intervals. Before discussing each component in detail, a brief overview of the waves and intervals is given.
Are leads 1 and aVL contiguous?
I & aVL Lateral Wall Leads V5 and V6 are positioned on the left lateral chest and view the lower lateral wall of the left ventricle. Since Leads 1, aVL, V5 and V6 all view the lateral wall of the left ventricle they are considered contiguous.
What does it mean if aVR is positive?
ARRHYTHMIAS. The morphology of the P wave in lead aVR can be used to differentiate atrial tachyarrhythmias. A positive P wave in aVR during tachycardia favours atrioventricular nodal re-entry tachycardia (Figure 6) (11). A negative P wave in aVR suggests a focal right atrial tachycardia (Figure 7) (33).
How many types of ECG are there?
There are 3 main types of ECG: a resting ECG – carried out while you’re lying down in a comfortable position. a stress or exercise ECG – carried out while you’re using an exercise bike or treadmill.
What is the difference between EKG and ECG?
What is the difference between and ECG and EKG? There is no difference between an ECG and an EKG. Both refer to the same procedure, however one is in English (electrocardiogram – ECG) and the other is based on the German spelling (elektrokardiogramm – EKG).
