Malignant Ventricular Arrhythmias Resulting From Drug-Induced QTc Prolongation: A Retrospective Study
Journal: Journal of Clinical Medicine Research
Year: 2018

In some probably genetically predisposed subjects, the occurrence of symptoms (dizziness, lipothymia, syncope ) and/or documented arrhythmic events (TdP), is related to intake of certain drugs (antiarrhythmics, antimicrobials such as quinolones and macrolides, etc.). Nevertheless, in our diLQTc patients, QTc duration didn't predict occurrence of symptoms, or arrhythmic events. Thus, other determinants should be postulated to clarify why sometimes diQTc prolongation propitiates ventricular malign
