Correlation of Nasal Septum Deviation With the Risk of Cardiac Arrhythmia and the Effect of septoplasty

Abstract

Background and objectives:Nasal obstruction is a highly prevalent problem worldwide that can negatively affect quality of life and can result in many cardiac complications. One of the common causes of nasal obstruction is a devi- ated nasal septum. The aim of this study was to examine the risk of ventricular and atrial arrhythmias in patients who were diagnosed with deviated nasal septum and to find out the effect of septoplasty on the risk of cardiac arrhythmia through studying P wave dispersion and corrected QT dispersion values. Methods: The study involved 45 patients with nasal septal deviation whom underwent septoplasty. Electrocardiographic records were used to calculate both P wave dispersion and corrected QT wave dispersion both preoperatively and 6 months postoperatively and compar-ing them with control group. Results: Pre-operatively, the mean + SD of the P wave dispersion among cases was55.33 + 12.17 milliseconds which was significantly higher than the mean of the controls (42.0 + 10.36 milliseconds). The mean of the QT corrected dispersion was also significantly higher among cases than the controls (51.09 vs.44.53 milliseconds respectively). In addition, P wave dispersion and QT corrected dispersion values were significantly greater in preoperative patients with deviated nasal septum when compared with the same patients postoperatively. Conclusions: atients with severe nasal septal deviation are at risk of development of cardiac arrhythmia, and sep-toplaty relieves upper airway obstruction and will eventually reduce the risk of development of cardiac arrhythmia.
