Overview

There are no established diagnostic study of choice for dextrocardia. Despite that, many diagnostic studies may be useful, including the electrocardiogram and the chest x-ray which are both inexpensive and may be very suggestive of this condition.

Diagnostic Study of Choice

There are no established diagnostic study of choice for dextrocardia.
Despite that, many diagnostic studies may be useful, including the electrocardiogram and the chest x-ray which are both inexpensive and may be very suggestive of this condition.

Chest X-ray

May show the following changes:^[1]
- Cardiac apex pointing to the right
- Right-sided aortic arch
- Right hemidiaphragm presenting at a lower level compared to the left.

Electrocardiogram

ECG may be helpful in the diagnosis of dextrocardia. Findings on an ECG suggestive of/diagnostic of [disease name] include:^[2]^[1]
- Inversion of P wave in leads I and aVL
- Dominant S wave in leads I and V1 to V6
- Reversed R wave progression in chest leads
- Low voltage QRS in V4 to V6
- Extreme QRS axis
- Flattened T wave in V4 to V6 and aVR
- Inverted T wave in lead I and aVL
