Dextrocardia is a congenital defect in which the heart is situated on the right side of the body. There are two main types of dextrocardia: dextrocardia of embryonic arrest (also known as isolated dextrocardia[citation needed]) and dextrocardia situs inversus. Dextrocardia situs inversus is further divided.

Dextrocardia of embryonic arrest
In this form of dextrocardia, the heart is simply placed farther right in the thorax than is normal. It is commonly associated with severe defects of the heart and related abnormalities including pulmonary hypoplasia.[1]
Dextrocardia situs inversus
Dextrocardia situs inversus refers to the heart being a mirror image situated on the right side. For all visceral organs to be mirrored, the correct term is dextrocardia situs inversus totalis.
Dextrocardia is believed to occur in approximately 1 in 12,000 people.[2]
Kartagener’s syndrome occurs in approximately 1 in 25 of totalis. This disorder affects the sinus and bronchial cilia causing constant sinus and bronchial symptoms that medication cannot rectify. With Kartagener's both are usually present all year rather than being seasonal.
Although statistically people with dextrocardia situs inversus do not have any medical problems from the disorder, some[vague] are prone to a number of bowel, esophagus, bronchial and cardiac problems.[vague] Some of these conditions can be life threatening if left unchecked.
Diagnosis
Medical diagnosis of the two forms of congenital dextrocardia can be made by ECG[1] or imaging.
Technical dextrocardia
Technical dextrocardia refers to an ECG reading that has no basis in the patient's anatomy. This apparent presentation of dextrocardia is caused usually by the technician inadvertently swapping the limb leads on a 12 lead ECG. Usually this would show as an extreme axis deviation.
Management
ECG leads must be placed in reversed positions on a person with dextrocardia. In addition, when defibrillating someone with dextrocardia, the pads should be placed in reverse positions.[citation needed] That is, instead of upper right and lower left, pads should be placed upper left and lower right.
