What is the meaning of precardial shock?

The heart muscle, like any other muscle, consists of a huge number of muscle fibers, and they all work as a whole. For some reason, the synchronism of contraction of muscle fibers is disrupted, they begin to work inconsistently, which leads to cardiac arrest and death. With the help of a precardial stroke on the sternum, you can make the heart earn as synchronously as before. The purpose of delivering such a blow is to shake the chest as much as possible, which can become the impetus for the launch of a stopped heart. Often, a stroke restores the heartbeat and regains consciousness.
