A continual "lub-dub, lub-dub" is a common way to characterize the sounds. The mitral valve and tricuspid valve closing is the source of the first "lub-dub." Following the first "lub-dub," the second "lub-dub" is made by the aortic and pulmonary valves shutting.
A blood backflow brought on by the heart's mitral valve failing to seal securely. When the mitral valve of the heart fails not close completely, blood can flow backward inside the heart, a condition known as mitral valve regurgitation. Breathing difficulties, weariness, dizziness, and an erratic, fluttering heartbeat are all symptoms. Treatment might not be necessary for everyone. Between the heart's two right chambers is where the tricuspid valve is located. There are three little flaps of tissue that make up the tricuspid valve (called cusps, or leaflets). These valve flaps open to let blood to flow from the right atrium, which is the upper chamber, to the right chamber, which is the lower chamber (right ventricle).

I think you meant disease, in which case-
An autoimmune disease is a condition in which your immune system mistakenly attacks your body.
The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them.
Normally, the immune system can tell the difference between foreign cells and your own cells.
In an autoimmune disease, the immune system mistakes part of your body, like your joints or skin, as foreign. It releases proteins called autoantibodies that attack healthy cells.
Some autoimmune diseases target only one organ. Type 1 diabetes damages the pancreas. Other diseases, like systemic lupus erythematosus (SLE), affect the whole body.
