Since the first telecardiogram recorded in ...
What is the name of the triangle that is a neutral point?
As a result, they form an equilateral triangle. Hence it's called the Einthoven's triangle, named after Willem Einthoven who invented the first practical ECG. Keep in mind that RL is neutral (also known as point zero where the electrical current is measured).
How are 12 views collected?
These 12 views are collected by placing electrodes or small, sticky patches on the chest (precordial), wrists, and ankles. These electrodes are connected to a machine that registers the heart's electrical activity.
Why is it important to place electrodes correctly?
Exact placement of each electrode on the patient is important. Incorrect placement can lead to false or misleading diagnosis.
Why do you cross your arms on your stomach?
For patients that do not fit comfortably on the bed or exam table due to size, ask them to cross their arms on their stomach to reduce muscle tension and movement. Unless you're performing a stress ECG test, ask the patient to lie still and quietly until the test is done.
What is a lead ECG?
A lead is a glimpse of the electrical activity of the heart from a particular angle. Put simply, a lead is like a perspective. In 12-lead ECG, there are 10 electrodes providing 12 perspectives of the heart's activity using different angles through two electrical planes - vertical and horizontal planes.
How does an electrocardiograph generate an ECG lead?
Figure 16. The electrocardiograph generates an ECG lead by comparing the electrical potential difference in two points in space. In the simplest leads these two points are two electrodes (illustrated in this figure). One electrode serves as exploring electrode (positive) and the other as the reference electrode. The electrocardiograph is constructed such that an electrical current traveling towards the exploring electrode yields a positive deflection, and vice versa.
What is Mason Likar's lead system?
Mason-Likar’s lead system simply implies that the limb electrodes have been relocated to the trunk. This is used in all types of ECG monitoring (arrhythmias, ischemia etc). It is also used for exercise stress testing (as it avoids muscle disturbances from the limbs).
What is an ECG lead?
An ECG lead is a graphical description of the electrical activity of the heart and it is created by analysing several electrodes.
What is the order of the leads in the Cabrera system?
In the Cabrera system, the leads are placed in their anatomical order. The inferior limb leads (II, aVF and III) are juxtaposed, and the same goes for the lateral limb leads and the chest leads. As mentioned earlier, inverting lead aVR into –aVR improves diagnostics additionally.
What is the lateral limb lead?
Lead aVL, I and –aVR are called lateral limb leads, because they primarily observe the lateral wall of the left ventricle. Note that lead aVR differs from lead –aVR (discussed below). All six limb leads are presented in a coordinate system, which the right hand side of Figure 18 (panel A) shows.
Where are the limb leads placed?
Leads I, II, III, aVF, aVL and aVR are all derived using three electrodes, which are placed on the right arm, the left arm and the left leg. Given the electrode placements, in relation to the heart, these leads primarily detect electrical activity in the frontal plane.
What is the difference in electrical potential?
Electric potential difference is defined as a difference in electric potential between two measurement points. In electrocardiology these measurement points are the skin electrodes. Thus, the electrical potential difference is the difference in the electrical potential detected by two (or more) electrodes.
How to identify V4 and V3?
V4 should be placed before lead V3. First identify the midclavicular line. This is the midpoint of the left clavicle (collarbone). Start by finding the suprasternal notch at the top of the sternum (breastbone). Move your finger slightly to the left to find the end medial edge of the clavicle. Put your fingers from the other hand on the outside of the left shoulder. Move them slightly forward and to the midline about half an inch to find the distal end of the left clavicle. From there, imagine the midpoint on the clavicle and mark it visually or with a finger. Imagine all line running straight down from this point on the clavicle. From the intercostal space associated with V2 (4th intercostal space), move your fingers down over the 5th rib to the 5th intercostal space. Place lead V4 in the 5 th intercostal space, in the midclavicular line.
What is the sternal ridge?

Clavicle – collarbone.
What is the Latin word for ribs?
Costa – Latin word for rib. Costal – in relationship to the ribs. Intercostal space (ICS) – the area of soft tissue between the ribs (e.g. 2 nd ICS is the area between the 2 nd and 3 rd ribs) Sternum – Breastbone.
Where is the sternal ridge located?
The sternal ridge/angle (“angle of Louis”) is at the level of the 2 nd intercostal space.
Where to place lead V5?
To place the electrode for lead V5 start in the intercostal space associated with lead V4 (5th intercostal space) and move to the left to an imaginary line associated with the front portion of the armpit going down toward the anterior hip.
Where is the lead V1?
Placement of Lead V1. Locate the sternal notch (Angle of Louis) by feeling the top portion of the breast bone, and moving your fingers downward until you feel a bump. Move your fingers to the right, off of the bump, and you will feel some soft tissue in between the 2nd and 3rd rib. This is the 2nd intercostal space.
Which lead is used to measure the lead that would correspond to V5 on a 12 lead?
Brown is typically placed left anterior axillary, to measure the lead that would correspond to V5 on a 12 lead. Midaxillary would be closer to V6. Between that and lead II, you should be able to pick up the majority of ischemic events. IIRC the textbook answer is that 90% of cardiac ischemia will be visible in either II or V5. Lead II typically produces the cleanest waveform for assessing rhythm since the p waves are nice and big. V5 is the single best for watching the left ventricle.
What is the brown lead on an EKG?
The brown lead is the "V" lead on a typical EKG. This means you can place it on the body to reflect V1-V6. In anesthesia and the operating room we monitor lead V5 for ischemia as PGG posted. I recommend you look at a picture of V-V6 in order to see the property location for that particular V lead.
What is the best way to clean grease off a patient's body?
A quick wipe down with a alcohol pad, cleans the grease off most patients.
What does 1 through 6 mean?
1 through 6 represents placement of the V leads (V1-V6). Again, we like to monitor lead II and V5 in the operating room so look at the picture above labeled "5".
What is green lead?
Green is a ground lead that just reduces artifact. Traditionally placed toward the right leg. I honestly couldn't tell you if it matters at all where it goes, but it might matter some.
Does bumping it serve any purpose?
It is very likely that it does not need any further discussion and thus bumping it serves no purpose.
What is the top of a cuff?
The top of the cuff is 23cm below the right atrium. If oscillometric machines are used repeat steps 1-3 and record readings.
How wide should a cuff be?
Choose a cuff whose width is 40%-50% of limb circumference of the limb to which you will attach it, and round up to the next sized cuff if in between. The inflatable part of the cuff (bladder) should be long enough to encircle 50%-80% of limb.
Where is the lead 3 electrode?
Lead III: LL - RA: Left hindleg (left leg) electrode (+) placed on the loose skin at the left stifle in the region of the patella - right foreleg (right arm) electrode (-) placed just below the point of the elbow on the back of the right forearm.
Where to place pulse oximeter?
The common locations include hairless, minimally-pigmented areas of the body including the lip, pinnae, prepuce, vulva, and interdigital space. Essentially, the probe can be placed on any area with a pulsating arteriolar bed.#N#Transillumination pulse oximetry of the tongue has been documented as a viable method of monitoring, but not everyone has the equipment available to place a transilluminating pulse oximeter on the tongue. A reflectance pulse oximeter sensor has the light source and the light detector in a side-by-side configuration rather than in opposition.
Can you use a pulse oximeter on your tongue?
Transillumination pulse oximetry of the tongue has been documented as a viable method of monitoring, but not everyone has the equipment available to place a transilluminating pulse oximeter on the tongue. A reflectance pulse oximeter sensor has the light source and the light detector in a side-by-side configuration rather than in opposition.
What are the little lights on a tele monitor?
Most of them have little lights that will cycle through when they are placed right and just around the little lights are color coded rings on a figure of a chest. If you have a light on it isnt making contact. Most tele monitors are like that anyway. Check both sides of the tele transmitter. 1 Likes.
What does the tele box tell you?
I second meownsmile's post. The tele boxes will tell you where to put the leads.
How often do you have to remove electrodes?
You DO have to remove and change the electrodes every 24 to 48 hours. You need to check the patients skin for irritation and allergic reactions. Then when you reapply the electrode put them in a slightly different place as before.
Why do you put black over red?
then Black over red because SMOKE OVER FIRE. Since you've already got leads on the right side, the black and red have to go on the left, it's what you've got left. Put them in the same positions as the leads on the right side.
Do you shave hair off before putting down stickers?
Sometimes folks are diaphoretic and they fall off from the moisture. Also, if someone's got a hairy chest, you'll want to shave the hair off before putting the stickers down. Saves them some pain on removal and you'll pick up the waveform better when the stickies are right on the skin.
Do you have to change diaphoretics?
You don't have to change them on a regular basis, the less removing and replacing the better for the patient's skin. Sometimes folks are diaphoretic and they fall off from the moisture.
