Preoperatif Uzun QT Saptanan Hastaların Demografik ve Klinik Özelliklerinin Retrospektif Değerlendirilmesi.

Objective: Long QT syndrome (LQTS) is a rarely seen syndrome that may present with prolonged QT interval and T wave abnormalities in the electrocardiogram (ECG) that may cause ventricular arrhythmia attacks and has a mortal course may be presented with. Prevention of arrhythmic complications is of great importance in the anaesthesia induction and maintenance of these patients. However, in routine preoperative evaluation, patients with prolonged QT can often be overlooked. In this study of ours, we evaluated the frequency of LQTS, the demographic characteristics of patients, and the reasons for requesting cardiology consultations in the preoperative ECGs. Method: The preoperative ECGs of patients scheduled for elective operation in our hospital between March 1,2019 and March 1,2020 were analysed retrospectively. Patients whose duration of QTc was ≥480 ms in women and ≥460 ms in men were defined as LQTS.Preoperative outpatient clinic data and cardiology consultation were evaluated using the protocol numbers of these patients. The demographic and clinical features of the patients were analysed. Results: Among the ECGs obtained in the pre-operative period, LQTS was detected in 45 patients, 13 women and 32 men. It was found that only n=25(55.6%) patients were requested for cardiology consultation. When the reasons for the request for cardiology consultation were examined, it was observed that the most frequent indication for consultation was organizing antiaggregant treatment and for examination of acquired heart diseases due to advanced age (n=7, 28% and n=6, 24%, respectively). It was observed that cardiology consultation was not requested for any patient due to LQTS. Conclusion: In the analysis, it was found that the frequency of requesting cardiology consultation was relatively low in patients with LQTS, and consultation was requested for elderly patients with lower exercise capacity under antiplatelet-anticoagulant treatment who were generally followed by the cardiology clinic. Since LQTS is a condition that can be overlooked especially when due attention is not paid, there is a need to increase attention. [ABSTRACT FROM AUTHOR]
