Leads V1 and V2 on an ECG monitor which part of the heart?

Leads V1 and V2 on an ECG monitor are positioned on the chest in such a way that they primarily provide information about the septal region of the heart. These leads are placed over the right side of the sternum and focus on the interventricular septum, which separates the left and right ventricles.

When observing the ECG readings from V1 and V2, specific changes can indicate issues such as ischemia or infarction in this area. Therefore, the presence of ST segment elevation in these leads, for example, may suggest an anteroseptal myocardial infarction, affecting the blood flow to the septum.

The other options refer to areas of the heart typically associated with other leads; for instance, the anteromedial wall is primarily monitored by leads V3 and V4, while the lateral wall is assessed by leads I, aVL, V5, and V6. The inferior wall is evaluated through leads II, III, and aVF. Thus, V1 and V2 are specifically associated with the septum, making this the correct choice in the context of understanding ECG lead placement and heart wall dynamics.
