Why We Simulated?
SVT is often described as "like the buses": you go around without seeing any, and then three turn up at once. It is seen in both adults and children. Understanding the management and the signs of compromise is important so that the treatment is escalated appropriately.
In the stable patient it may resolve with some simple and non-invasive techniques (check out the results of the REVERT trial summarised in 'Further Resources').
It is also necessary to think about the management beyond ED as it can be easy to cardiovert the patient (either chemically or electrically) and then discharge them without thinking what happens next.
