Cardia myocytes. These special muscle cells can produce myoclonic movement (rythmic contractions initiated without input from the nervous system) when bathed in fluid containing oxygen and glucose.
Actually, the heart is surrounded by a pericardium and its wall is made of 3 layers. Therefore, the terminology "4 walls of the human heart" is quite misleading. So, from outside to inside, we have: *Pericardium *Heart wall: -Epicardium -Myocardium -Endocardium
The myocardium is the middle layer of the walls of the heart, made of cardiac muscle, that contracts to push out blood.

The human heart has 4 sides.
The heart is composed of cardiac muscle.
The cell walls of the heart are myocardial tissue. Myocardial cells are the only cells in the body with intercalated disks. These disks allow the cells to have intrinsic automacioty, meaning if left to their own devices they will keep a steady heart beat without prompting from the SA node.
The atrial walls inside the heart are made of endothelium and are called endocardium. They are made of the same tissue as the insides of veins and arteries.

Behind Mansion Walls - 2011 A Bankrupt Heart was released on: USA: July 2013
The His-Purkinje system is the part of the heart's electrical system that follows the outer walls of the ventricle.
If you dig underground and dig in the walls you can get heart scales.
