Long QT syndrome (LQTS) is described as the development of sudden syncope attacks or death as a result of ventricular tachycardia (VT) episodes that might be observed as elongated QT interval in electrocardiography (ECG). Implantable Cardioverter Defibrillator (ICD) is recommended as first-line treatment for the condition in guidelines. We aimed to present an adolescent recently diagnosed with Bipolar Disorder (BD) who had LQTS that was treated with ICD, discussing her follow up and treatment along with relevant literature.Psychiatric assessment of the case that applied to our child psychiatry unit due to manic symptoms were carried out by using Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) criteria. Symptom severity was monitored via Young Mania Rating Scale scores (YMRSS).The case met criteria for Bipolar Disorder Type I (BD-I). She had improvement in her mood symptoms with treatment regimen as risperidone 3 mg/day, valproate 1000 mg/day and lorazepam 1 mg/dayi after her 2-week follow up as well as no reported ICD activity, reflecting fine cardiac functions and rhythm.LQTS is a serious health issue for children and adolescents diagnosed with BD. This condition should be kept in mind especially in cases where familial risk factors are present and precautions need to be maintained upon required assessments. These cases need to be closely monitored due to risk factors related to both BD and LQTS, in a multidisciplinary fashion, involving both psychiatry and cardiology divisions.
