Answer:

Romano-Ward syndrome (RWS) is a form of long QT syndrome, a heart condition that causes the heart muscle to take longer to recharge between beats than usual.

Explanation:

The heart muscle (myocardium) has the ability to contract and relax in a very precise rhythm so that each cavity, in order, is filled and then empties of the blood it contains. Romano-Ward syndrome is the most common form (autosomal dominant form) of long QT syndrome characterized by an abnormality of cardiac electrical activity that can be diagnosed by recording the electrical impulses of the heart. Despite having a normal anatomy, the heart has electrical dysfunction (abnormally long QT interval) .This syndrome is associated with an increased risk of syncope (fainting), loss of consciousness, heart rhythm disturbances, and even cardiac arrest, which can occur due to efforts or the administration of certain medications. The most frequent causes of the syndrome are mutations in the KCNQ1, KCNH2 and SCN5A genes (these encode proteins that form channels through the cell membrane), these channels transport ions such as potassium and sodium, inside and outside the cells. In heart muscle cells, these ion channels play critical roles in maintaining the heart's normal rhythm.

Some people will realise that they are dreaming while the dream is happening​
Ne4ueva [31]

Answer:

That is true; after becoming aware of the fact you are in a dream, not knowing how to wake up, I suspect it is a frightening experience. On the same token, by becoming of your inward presence, you have the ability to change your thoughts, and can change the world inside of your head. These are called lucid dreams. If you ever become aware of the fact you are inside a dream, what would you do? Would you try to wake up? Would you try to make the world of your dreams? Even if you wanted to, do you think you'd be able to? If you wish to learn how to experience lucid dreams, there are many tutorials online, teaching you step-by-step how to lucid dream.
