What is the correct sequence for placing the chest leads V1-V6?

The correct sequence for placing the chest leads V1-V6 is V1, V2, V3, V4, V5, V6. This order follows the standard anatomical locations for placing the electrodes in an electrocardiogram (ECG or EKG), ensuring accurate electrical readings from the heart.

V1 and V2 are typically placed on either side of the sternum in the fourth intercostal space, with V1 at the right side and V2 at the left. Following these, V3 is placed directly between V2 and V4. V4 is positioned at the fifth intercostal space, at the midclavicular line. V5 is placed in line with V4 at the same horizontal level, positioned anteriorly to the left axillary line, and V6 is placed at the same level as V4 and V5, but in the midaxillary line.

This systematic and standardized placement is critical because it allows for consistent reads across different patients and situations, making the resulting data reliable for diagnosing various heart conditions. Each lead provides a unique view of the heart's electrical activity, and any deviation from this order can affect the readings, potentially leading to misinterpretation.
