Evaluation of the risk of sudden cardiac death in obstructive sleep apnea syndrome patients with Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio
Abstract
Aims: Obstructive sleep apnea syndrome (OSAS) is a disorder characterized by recurrent collapse of the upper airway during sleep. OSAS is associated with an increased risk of cardiovascular morbidity and mortality. Tpeak to Trend (Tp-e) interval, the Tp-e interval/QT interval (Tp-e/QT) ratio, and the Tp-e interval/corrected QT interval (Tp-e/QTc) ratio, are associated with ventricular arrhythmias and sudden cardiac death in various disease groups. we aimed to investigate the relationship between changes in the new arrhythmia markers Tp-e interval, Tp-e/QT and Tp-e/QTc ratios in OSAS patients.
Methods: The study looked at 45 people with OSAS (32 men) over the age of 18 and 43 healthy people (27 men) who were diagnosed with OSAS through polysomnography in a sleep lab. Tp-e interval, Tp-e/QT and Tp-e/QTc ratios were calculated on the ECG.
Results: The QT interval was shorter in the patient group than in the control group, in contrast to the QTc interval, which was comparable between groups (p = 0.006 and 0.810 in the patient and control groups, respectively). The Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio were significantly higher in PHPT patients included in the patient group compared to those included in the control group (p<0.01 in total).
Conclusion: The Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were prolonged in OSAS patients. These findings suggest that OSAS patients may be predisposed to severe ventricular arrhythmias.
