👉 The term "intrapericardiac" is used to describe a region within the heart that lies between two chambers of the heart. This region contains blood vessels, including the sinoatrial node (Sano), which is responsible for initiating and maintaining the electrical activity in the atria of the heart. The intrapercicardial region also includes vessels that supply blood to the pericardium, which is a protective layer surrounding the heart's walls.
