Background and objectives: We aimed to evaluate the marker of ventricular arrhythmias such as Tp-e/QT, Tp-e/QTc, Tp-e/JT and Tp-e/JTc ratios in Small Heart Syndrome female patients.
Methods: A total of 94 female, including 47 small-heart and 47 normal-heart patients, who applied from March 2018 to February 2020 were included in the study by calculating their cardiothoracic ratios (CTR) from the chest x-ray. QTmax, QTmin,QRS, JT and Tp-e intervals were measured. In addition, Tp-e/QTmax, Tp-e/QTc max, Tp-e/JT and Tp-e/JTc rates and QTc max, QTc min, cQTd and JTc intervals were calculated.
Results: cQTd (24.246 ± 9.046 ms vs. 35.495 ± 14.358 ms, p < 0.001), Tp-e (67.32 ± 11.661 ms vs. 72.67 ± 11.028 ms, p = 0.04), Tp-e/QTc max (0.166 ± 0.028 vs. 0.181 ± 0.027, p = 0.012), Tp-e/JTc (0.214 ± 0.038 vs. 0.232 ± 0.034, p = 0.022) values were significantly higher in small heart patient group. QTc min (379.34 ± 20.064 ms vs. 364.71 ± 23.149 ms, p=0.004) values were significantly lower in patient group.
Conclusion: Compared to control group potential ECG repolarization predictors were significantly increased in Small Heart Syndrome patients.
