      Taskin et al (Int J Pediatr Otorhinolaryngol 2022;162:111297; PMID 36088733) collected data on children undergoing cochlear implantation for sensorineural hearing loss at the University of Health Sciences Istanbul Research and Training Hospital from 2019–2020. Sixty children (mean age 6.5 years) were included in the study. Electrocardiography (ECG) revealed various minor or nonspecific abnormalities in 25% of patients but importantly identified 4 cases reported as long QTc, although 2 were only borderline. The other 2 patients with definitive QTc prolongation subsequently were diagnosed with long QT syndrome type 1, which was confirmed by genetic testing. Notably, both cases were associated with consanguineous marriage, which was also present in 30% of all study subjects. The authors concluded that ECG and cardiac examination may be important components of the evaluation of patients with sensorineural hearing loss, with the potential to reveal the presence of primary arrhythmia syndromes.
