What does a right axis deviation suggest?

What does a right axis deviation suggest?

• A. Possible myocardial infarction
• B. Possible left ventricular hypertrophy
• C. Possible right ventricular hypertrophy or pulmonary conditions
• D. Electrical conduction delay

Answer: (C)

A right axis deviation on an ECG indicates that the electrical activity of the heart is oriented more toward the right side than what is considered normal. This finding often suggests the presence of right ventricular hypertrophy or various pulmonary conditions. In conditions such as chronic obstructive pulmonary disease (COPD) or pulmonary hypertension, the increased workload on the right side of the heart can lead to right ventricular hypertrophy. These conditions can also shift the cardiac axis to the right due to anatomical or functional changes in the heart. Thus, when a right axis deviation is observed, it serves as an important marker for clinicians to investigate possible underlying issues related to the right side of the heart and respiratory functions, making it a significant indicator in ECG interpretation.
