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.
Answer:
secs? Are you trying to say copulation
Explanation:
There are a few actions that a person can take to help ensure his or her ability to participate in physical activity throughout life. One is planning, plan and create a schedule to ensure you have time and are available. Another is commitment, once you decide, commit.
But since you now just proved the options, the answer is unlimited exercise, though, this does not mean to over exercise.
Calm down. First, it is IMPOSSIBLE to stay focused for 10 hours a day so don't even attempt. I would say three hours a day (WITH PLENTY OF BREAKS) is the best amount if you're so determined. You have a life to live and you will stress yourself out too much. Being stress free is a part of preparing for exams. You have 10 months. Create a study schedule. Use the weekdays with 3 hours to prepare for the harder subjects and weekends and 1.5 hour to prepare for easier subjects. Nobody has to study 10 hours a day. Not even those in medical school. Continuous practice and trying to see how ideas relate to everyday life will really help. Think of some weird connections to help remember a concept. I'm not sure what these tests are for and why you're taking them but just relax. Honestly.
