, Medical Student. The heart, actually, is located in the center of the chest, behind the sternum (or the breastbone). However, a part of it is slightly offset to the left, as you can figure out from the picture above. For understanding this, I think prerequisite knowledge of the heart's basic anatomy is required.
The heart is not exactly located on the left side of the chest. With a size of your fist, your heart lies between the left and right lungs, behind your breastbone, and is slightly towards the left. Place your right palm in the middle of your chest. Move your hand a bit to the left, and thatâs the exact location of your heart.
