/api/v1/reaction/electrocardiogram-qt-prolongedReference statistics only. FAERS reports are voluntarily submitted and are not incidence rates, safety signals, or causal evidence. The drugs below are ranked by how often this reaction appears on FAERS reports for each drug — high share does not mean the drug caused the reaction, and absence from this list does not mean the reaction never occurred. This is not a symptom checker.
DefinitionNLM MeSH D008133
A condition that is characterized by episodes of fainting (SYNCOPE) and varying degree of ventricular arrhythmia as indicated by the prolonged QT interval. The inherited forms are caused by mutation of genes encoding cardiac ion channel proteins. The two major forms are ROMANO-WARD SYNDROME and JERVELL-LANGE NIELSEN SYNDROME.
