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.
Small saphenous vein travels up the back of your calf and ends behind your knee. It drains into your popliteal vein.
What is the saphenous vein?
- Blood vessels in your legs called saphenous veins assist in returning blood from your feet and legs to your heart.
- Each of your legs has two saphenous veins.
- Your large saphenous vein and tiny saphenous vein are known by these names.
- The longest vein in your body, the great saphenous vein runs from the bottom of your foot to the top of your thigh.
- It is also referred to as the long saphenous vein.
Function of saphenous vein:
- The circulatory system in your body includes saphenous veins.
- Your body's circulatory system maintains a steady flow of blood throughout it.
- Your blood is always moving.
- That's because it's responsible for supplying all of your organs and tissues with oxygen and nutrients.
- Every minute of every day, this occurs.
Therefore, saphenous vein drains into your popliteal vein.
