A member asked:
Do antibiotics and heart meds cause long qt syndrome?
A doctor has provided 1 answer
Secondary Long QT: Both can. Several antibiotics and antiarrhythmic medications, and other medications, can prolong the qt interval on the ECG increasing the risk for certain, potetially life threatening, heart rhythms. Secondary long qt (from meds) can be made worse when taking certain heart medications (antiarrhythmics) and then adding antibiotics to the mix. Ask md if new medications are ok to add.
