While we wait for the appointment, she remains connected to a cardiac event recorder called The King of Hearts. Some tachycardias can cause sudden death in young athletes however more often it is a structural abnormality that went undiagnosed that leads to such deaths. Your daughter has had most of the necessary tests already, other than the king of hearts monitor, the EP cardiologist may want to do one other test and that is a study of your daughter's cardiac electrical system with what is called an EP study-an outpatient procedure that takes up at least half the day with all the preparation. Many of the answers you are looking for really require a specific diagnosis as the answer as such is highly dependent on the type of rhythm abnormality. I hope this information is useful.
