Magnesium sulfate may play a role ...
Background:There are two trains of thought in using transthoracic direct current cardioversion (DCCV) when it comes to converting atrial fibrillation. The first is an escalating energy approach which allows cardioversion to occur at the lowest energy for each individual patient ...
