Back to Glossary

A rare congenital condition where the heart is on the right side of the thorax. Electrocardiographically, this results in right axis deviation and positive QRS complex in aVR with upright P- and T-waves.

Examples

ECG Showing Dextrocardia

Dextrocardia

The size of the QRS complexes decrease across the precordium. Typically, the complexes increase in amplitude across the precordium. Additionally, there is an unexplained right axis deviation. This patient went for emergent catheterization because of the ST morphology in the inferior leads and was ultimately diagnosed with myopericarditis.
