Overview
Electrocardiogram may be used as a diagnostic tool in the evaluation of an atrial septal defect. ECG findings associated with dextrocardia include an R wave inversion.
Electrocardiogram
An ECG may be helpful in the diagnosis of dextrocardia. Findings on an ECG suggestive of/diagnostic of [disease name] include:[1]
- Inversion of P waves.
It is possible to distinguish lead reversal and dextrocardia by watching the precordial leads. Dextrocardia will show an R wave inversion, whereas lead reversal will not.
The bottom EKG shows marked right axis deviation and loss of voltage across the precordium. There are also inverted P waves in leads I and aVL. The differential for inverted P waves in lead I and aVL is Dextrocardia vs Reversed Arm Leads. Since there is loss of voltage across the precordium this is Dextrocardia.
Special considerations
ECG leads must be placed in reversed positions on a person with Dextrocardia.
