Is sensitive tissue in the right atrium wall that begins the heartbeat called atrioventricular node?

No, the sensitive tissue in the right atrium wall that begins the heartbeat is called the sinoatrial (SA) node, not the atrioventricular (AV) node. The SA node is often referred to as the heart's natural pacemaker as it initiates the electrical impulses responsible for coordinating the heartbeat. The AV node is located in the septum between the atria and ventricles and serves to delay the impulse to allow the atria to fully contract before the ventricles do.

What is in your heart?

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.
