Dextrocardia

n. abnormal condition in which the heart is on the right side of the body

Dextrocardia is a peculiar condition in which the heart is positioned on the right side of the chest while it is normally on the left (mirror-image). The name is derived from dexter in Latin meaning "on the right" and cardio meaning "of the heart".If the rest of the organ systems are reversed, the condition is called situs inversus. Individuals with both dextrocardia and situs inversus suffer a far lesser rate of congenital heart defects than do people with only one of the two conditions.When defibrillating someone with dextrocardia, the pads should be placed in reverse positions. That is, instead of upper right and lower left, pads should be placed upper left and lower right.

Noun
1. abnormal condition where the heart is located toward the right side of the chest
(hypernym) abnormality, abnormalcy, abnormal condition

The heart is reversed and is in the right side of the chest rather than in its normal location on the left. This is a true anatomic reversal. With dextrocardia, for example, the apex (tip) of the heart points to the right rather than (as is normal) to the left. Dextrocardia occurs in an abnormal condition present at birth (congenital) called Kartagener’s syndrome.
