Özet
Objective Spinal cord injury (SCI) can lead to significant cardiac arrhythmia. However, P-wave, QT dispersion, and risk factors in these patients have not been widely investigated. In this study, we assessed whether there is a relationship between electrocardiogram (ECG) parameters and risk factors in SCI patients. Methods The study population consisted of 85 SCI patients and 38 control subjects. P-wave durations were measured using 12 leads of the surface ECG. P-wave dispersion was defined as the difference between the P-wave maximum and P-wave minimum duration. QT dispersion was defined as the difference between the largest and smallest QT interval for any of the 12 leads (QTmax-QT-min). QT intervals were also corrected (QTc) in accordance with the heart rate using Bazett's formula (QT Interval/root[RR interval]). We also evaluated the independent risk factors for P-wave dispersion and QT dispersion in SCI patients. Results The P-wave minimum, P-wave maximum, QT minimum, and dispersion were significantly different between the control and SCI groups. There was no significant difference in P-wave dispersion, QT maximum, or QTc. Multivariate regression analysis showed that disease duration, glucose and high-density lipoprotein cholesterol (HDL-C) levels, and systolic tension were independent risk factors for P-wave dispersion. Conclusion Our results demonstrate that QT dispersion is related to SCI and that P-wave dispersion was linked to the duration of SCI, HDL-C and glucose levels, and arterial tension in SCI patients.
