Where is the V1 chest electrode located?

The V1 chest electrode is located in the fourth intercostal space, specifically at the right side of the sternum. This placement is crucial because V1 helps in assessing the heart's electrical activity from a right-sided perspective, which is important for identifying certain cardiac conditions such as right ventricular hypertrophy or changes in the right side of the heart.

By accurately positioning the V1 electrode in this location, healthcare providers can obtain critical information regarding the heart’s conduction system, particularly in the anterior and septal walls of the left ventricle, where any abnormalities can be indicative of underlying heart issues. Proper electrode placement is central to obtaining an accurate ECG readout, which is essential for diagnosing cardiac problems effectively.
