"Dextrocardia merely refers to the laterality of the heart, it says nothing about the orientation of the patient's other organs. Laevocardia is the term used for the heart being positioned on the left as is found in the vast majority of the healthy population."
"When approaching the chest radiograph in someone that appears to have dextrocardia it is important to exclude spurious dextrocardia first. This is by far the commonest cause of a dextrocardia-like appearance and is a technical error due to the radiographer/technician inadvertently flipping the image over in the mediolateral plane when processing the image. Therefore it is important to check the orientation marker on the image; usually in a spurious dextrocardia the marker will be on the 'wrong' side i.e. left marker on the right, or vice-versa."
"although persons with dextrocardia situs inversus tend not have any medical problems from the disorder, some are prone to a number of bowel, oesophageal, bronchial and cardiac problems where some of these conditions can be life-threatening if uncorrected"
"The most prominent abnormality recognised on ECG is the "global inversion" of standard (limb) lead I, with inversion of the P wave, QRS complex, and T wave, suggestive of either dextrocardia or limb lead misplacement (the RA, or right arm, lead was placed on the left and vice versa). Use of the precordial leads allows discrimination of these two entities, specifically by observing the precordial R wave progression."

"As one progresses from the right (represented by leads V1-V3) through the left precordium (leads V4-6), a progressive increase in the amplitude of the (first positive QRS deflection) R wave is expected, with poor R wave progression (PRWP) diagnosed when the amplitude of the R wave in V3 is"
