Identifying right ventricular hypertrophy is primarily assessed through which lead?

• A. Lead II
• B. Lead V3
• C. Lead V1
• D. Lead aVF

Answer: (C)

Identifying right ventricular hypertrophy (RVH) is primarily assessed through Lead V1 because this lead is positioned over the right ventricle and provides the most direct electrical view of the right ventricular activity. In RVH, you may observe several key findings in Lead V1, such as a prominent R wave or a deep S wave. These changes arise because the increased muscle mass of the right ventricle generates stronger electrical signals that can be detected in this lead. Furthermore, in Lead V1, the typical pattern associated with RVH includes a right axis deviation and an increased R/S ratio. This makes Lead V1 particularly sensitive in identifying RVH as it effectively captures the increased electrical activity of the hypertrophied right ventricle. Other leads, like Lead II, Lead V3, and Lead aVF, may provide useful information, but they do not offer the same focused assessment of the right ventricle, which is why Lead V1 is the lead of choice for evaluating right ventricular hypertrophy.
