In the case of right axis deviation, which leads would typically show a negative QRS complex?

In the presence of right axis deviation, the QRS complex may demonstrate specific deflections in various leads based on the electrical activity of the heart and the direction of the ventricular depolarization. When the heart’s electrical axis shifts to the right, it primarily affects the inferior leads.

In this context, leads aVF and V1 are of particular significance. Lead aVF, which looks at the heart from the foot's perspective, typically shows a positive QRS complex in normal conditions. However, in right axis deviation, the QRS complex may become negative due to the heart's altered electrical axis. Similarly, lead V1, positioned in the right precordial region, can also exhibit a negative QRS complex under these circumstances, reflecting the rightward shift.

This rationale establishes why leads aVF and V1 would typically show a negative deflection in right axis deviation, making this choice the accurate one. Other lead combinations would not typically present with the same negative deflections in this scenario.
