Where should the V1 lead be placed?

The V1 lead is part of the 12-lead electrocardiogram (ECG or EKG) system, which is used to assess the heart's electrical activity from multiple angles. For proper placement, the V1 lead is positioned on the right side of the sternum, in the fourth intercostal space. This placement provides a view of the electrical activity in the right side of the heart and allows for accurate detection of various cardiac conditions, such as right ventricular hypertrophy or specific types of arrhythmias.

Understanding the precise location for V1 is crucial as it forms the basis for interpreting the overall ECG effectively. Each lead offers a unique perspective on the heart's electrical impulses, and incorrect placement can lead to misinterpretation of the results.
