mean that physicians should try to control a patient's heart rate by using alternatives as a first line, such as beta - blockers or calcium blockers; if digoxin is used, use a low dose with careful clinical follow - up, evaluate potential drug interactions when starting new medications, and monitor digoxin levels,» the authors said «Patients should be aware of potential toxicity and see their physicians immediately in specific clinical situations, for instance if they experience
palpitations or syncope (fainting), as those may precede arrhythmic death,» they added.
