12 lead is recorded by how many lead wires?
12
How many views can be seen in a 12 lead ECG?
6
How many leads attach to the chest electrodes?
4
How many attach to the electrodes of the arm and legs/ shoulders and lower abdomen?
Standard leads, augmented leads, and chest leads
The 12 leads are made up of 3 different types of leads what are they?
3, 3, and 6
How many leads do standard leads, augmented leads, and chest leads
Recheck wires leads
If you attempt to record an ECG and no tracing is seen, what should you do?
Einthoven Triangle
Is formed by 3 of the limb electrodes: those on the right arm, the left arm, and left leg
Standard Limb Leads
First 3 leads are known as......
Bipolar Leads
Standard Limb Leads are also known as......
Because they measure the flow of electrical current in two directions at the same time.
Why are bipolar leads named that?
I, II , and III
What are the first 3 leads called?
Positive Deflections
What type of deflection do standard limb leads deflect?
Augmented Leads
What are the three second leads known as?
Because they are increased in size by the ECG machine in order to be interpreted
How do Augmented leads get their name?
Known as unipolar leads
What are Augmented leads also known as?
Because they measure toward one electrode on the body
Why are augmented leads also known unipolar leads?
aVR, aVL, and aVF
What are the leads on the augmented lead called?
It refers to the direction the lead is measuring: R is right arm, L is left arm, and F is foot
What do the R, L, and F refer to?
Verify the placement of the electrodes and lead wires to correct it.
What do you do if the aVR is not a negative deflection?
The last 6 leads are called the chest leads
What are the last six leads called?
It is called precordial leads located in front of (pre) the heart (cor).
What is another name for the chest leads?
Chest leads are unipolar since they are measured in one direction only
Are chest leads unipolar or bipolar?
Allows the physician to determine damage or problems in specific areas of the heart (Does not determine heart disease)
What do chest leads determine in the heart?
