Where is V3 located ECG?
Where is V3 located ECG?
12-Lead ECG Placement
| Code (AHA) | Code (IEC) | Location |
|---|---|---|
| V2 | C2 | Fourth intercostal space at the left sternal border |
| V3 | C3 | Halfway between leads V2 and V4 |
| V4 | C4 | Fifth intercostal space in the midclavicular line |
| V5 | C5 | Left anterior axillary line on the same horizontal plane as V4 |
What’s the color of the leads on an ECG?
The leads used in an ECG exam are color coded. There will be a chart on the ECG packaging that lets you know which color corresponds with which lead. The 6 chest leads are medically referred to as the “V” leads.
Where does the ECG lead go on the chest?
Press down firmly on the lead to fix it in place. If the patient has a defibrillator on their chest or has a pacemaker, do not place the ECG lead on the electrical device. Instead, move the lead 1 inch (2.5 cm) in any direction so it’s directly on top of the skin. The lead that goes on the left shoulder is usually color-coded black.
Which is the best interpretation of the ECG?
INTERPRETATION: The ECG in Figure 1 is shows normal sinus rhythm. All intervals and the axis are normal. There is no chamber enlargement. There are however, a series of alarming findings that were recognized by the emergency team.
Where does the action potential come from on an ECG?
On the ECG, an action potential wave coming toward the electrode is shown as a positive (upwards) signal. Here the ECG electrode is represented as an eye. The sinoatrial node (SA node) contains the fastest physiological pacemaker cells of the heart; therefore, they determine the heart rate.

Where does early repolarization of the ECG occur?
Early repolarization manifests in the inferolateral leads (II, III, aVF, aVL, I, –aVR, V4, V5, V6) and it appears that the risk of ventricular fibrillation is highest when ECG changes are evident in the inferior leads. Early repolarization are characterized by the following ECG changes: ST segment elevations with concave ST segment.
What does Einthoven’s triangle stand for in ECG?
Einthoven’s Triangle. Keep in mind that RL is neutral (also known as point zero where the electrical current is measured). RL doesn’t come up in ECG readings, and is considered as a grounding lead that helps minimize ECG artifact.
