Abstract
Background: Long QT syndrome is a myocardial repolarization disorder that results in long QT interval on the ECG.
Objective: The aim of this study is to determine the frequency of long QT syndrome in patients presenting to tertiary care hospital.
Materials and methods: This observational study was conducted at the department of cardiology, Hayatabad medical complex Peshawar from October 2014 to December 2021 to evaluate the prevalence of Long QT syndrome at admission and its influence on outcomes in CCU. The calculation of QTc using the formula by BAZETT, which suggests a range of >440 ms for males and >460 mm for females, was considered long. Furthermore, the illness's particulars, clinical observations and laboratory parameters were examined.
RESULTS: A total of 150 patients were enrolled in this study.There were 72 females and 78 males. At the time of admission to the CCU, Long QT Syndrome was frequently observed (32%). which dropped to 20.5% on day 3. Patients who suffered from long QT syndrome were found to have a high likelihood of adverse outcomes and were more likely to be admitted to the CCU of the hospital.
Conclusion: Our Study showed a high incidence of Long QT syndrome (32%) and was more likely to have adverse effects and had a higher admission in CCU.
