Dodge a "QT Storm" by Avoiding QT-Prolonging Meds In High-Risk Patients
We're getting questions about which meds or combos can "tip the balance" and lead to problems with QT prolongation.
Many commonly used meds can prolong the QT interval. But it rarely leads to torsades and sudden death in low-risk patients on one QT drug.
Watch for the highest-risk patients...where torsades is more likely. This includes patients with a history of QT prolongation, bradycardia, acute MI, low ejection fraction, etc. Also look for hypokalemia, hypomagnesemia, etc...especially with new diuretic use, vomiting, etc.
