You may have a condition called Dextrocardia (which is believed to occur in approximately 1 in 12,000 people). This is when the heart is located on the right side of the thorax. It was first seen and drawn by Leonardo da Vinci in 1452–1519. Please note, 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.
You may have another condition called Situs inversus. This is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions.
are you looking at the mirror ?
Go see a doctor. It could be a sign of serious lung infection.
The heart is in the center of your chest.
