Is right axis deviation a sign of heart problems?

Right axis deviation does not necessarily indicate a heart problem. An electrocardiogram (ECG) showing right axis deviation may be physiological, such as in individuals who are overweight or have a vertically oriented heart; such cases are usually not concerning. However, it could also be pathological, suggesting certain heart conditions. Among cardiac diseases, right ventricular hypertrophy is one of the common causes of right axis deviation, as seen in conditions like cor pulmonale and congenital heart disease. Myocardial infarction and bundle branch block can also lead to right axis deviation.

However, right axis deviation alone cannot confirm a diagnosis of heart disease. A comprehensive assessment should include the patient's clinical symptoms, other ECG findings, echocardiography, and additional tests. If the patient has no symptoms and all other tests are normal, the deviation may simply reflect individual variation or a physiological change. But if symptoms such as palpitations, chest tightness, or shortness of breath are present, or if other test results are abnormal, further evaluation for possible heart disease is necessary.

If you feel unwell, you should seek medical attention promptly.
