The Septum seperates the 2 sides of the heart.
The left side of the heart has larger muscle.
The muscle that separates the right and left side of the heart is called the interventricular septum and is just a continuation of the cardiac (Heart) muscle of the heart's walls.
The heart is composed of cardiac muscle, a special type of striated muscle. It contains valves lined with endocardium tissue. There are four chambers, two on the right and two on the left, where the entry chambers are the atria (right atrium, left atrium) previously known as auricles, and the pumping chambers are the ventricles.
The septum divides the left and right sides of the heart.
The heart is composed of the Right Atrium and Right Ventricle (collectively known as the Right Heart) and the Left Atrium and Left Ventricle (colelctively known as the Left Heart).
The type of muscle that is found in the right atrium is mainly the pectinate muscles. This is one of the four chambers of the heart.
On the right sie of the heart, there is a right atrium and right ventricle that are separated by the tricuspid valve or Atrioventricular valve. The left atrium and left ventricle are separated by the bicuspid or mitral valve.
In the human heart, contraction is initiated by a special modified heart muscle known as sinoatrial node. It is located in the right atrium. The SA node has the inherent power of generating a wave of contraction and controlling the heart beat. Hence, it is known as the pacemaker. Since the heart beat is initiated by the SA node and the impulse of contraction originates in the heart itself, the human heart is termed myogenic. The hearts of vertebrates and molluscs are also myogenic.
Right atrium
A Human Heart Beats Beacuse Of Blood Flow To The Right And Left Atricle and Upper and Lower Chambers Of The Heart. A more detailed and scientific answer would be: The human heart, as with any animals' heart, beats due to the brain sending an electrical impulse down the vagal nerve and through a nerve that is known as the "Pacemaker." This electrical impulse causes the heart muscle to contract, thus pumping blood through the body. The muscle contractions are what is known collectively as a heartbeat.

The interatrial septum separates the left atrium from the right atrium (the atria are the upper chambers of the heart).
