As a non-invasive yet valuable diagnostic tool, the 12-lead ECG r ecords the heart's electrical activity as waveforms. With proper lead placement and interpretation, an ECG can detect and monitor a host of heart conditions - from arrhythmias to coronary heart disease to electrolyte imbalance.

ECG 12 Lead Basics Cheat Sheet by sjacobs via cheatography.com/59806/cs/15660/ The Cardio vas cular System The heart forms a part of the greater cardio vas cular system which is respon sible for delivering efficient and continued oxygenated blood supply to the cells, tissues and organs of the human body.

Right sided 12 lead ECG lead placement The most useful lead is V 4 R, which is obtained by placing the V4 electrode in the 5th right intercostal space in the mid-clavicular line. ST elevation in V4R has a sensitivity of 88%, specificity of 78% and diagnostic accuracy of 83% in the diagnosis of RV MI.
Some patients will need all ten leads attached for twelve lead diagnostics. (The monitor combines two leads together to use as a focal point for some of the electrical tracings. This is why there are only ten leads attached.) Use the following guide for placing the six additional leads. V1 - 4th intercostal space, just to the right of the sternum.
Instead, memorize where each bipolar and unipolar lead goes and just use the guide on the ECG to double check if your placement is correct. A normal 12-Lead ECG has 6 limb leads and 6 precordial leads. These are all organized into 10 wires. Each lead is labeled accordingly.
SUSPECTED ACUTE CORONARY SYNDROME (ACS)? 1. Depress the soft button on the bottom left “12 Lead” 2. Turn large dial and select “Patient Age “ depress the round button to select the age. 3. The monitor will display “Acquiring ECG” during the data collection process . a. Keep the patient still during this phase to decrease artifact. 4.
To measure the heart’s electrical activity accurately, proper electrode placement is crucial. In a 12-lead ECG, there are 12 leads calculated using 10 electrodes. The limb leads can also be placed on the upper arms and thighs. However, there should be uniformity in your placement.
all use correct lead placement. There are 10 cables that must be attached to the patient. There are 2 arm leads, 2 leg leads, and 6 chest leads. Let’s start with the arm leads. It is important that you place each arm lead, right and left arm, in a symmetric location (same on the right as the left). Avoid bony prominences if possible, and
Limb leads should be placed on the extremities (if possible). Do not place over bony areas, open sores or broken skin. V1 – 4th intercostal space to the right (patient’s right) of the sternum. To find 4th intercostal space palpate directly under the clavicle for the first intercostal space. Palpate down to the 4th intercostal space.
