Abstract
We thank Yayla et al 1 for their interest in our paper entitled “The Assessment of Ventricular Arrhythmia Indicators Based on Electrocardiography in Patients With Differentiated Thyroid Cancer Followed Up With Levothyroxine Suppression.” 2
As we mentioned in our study, ventricular arrhythmia in patients with differentiated thyroid cancer under levothyroxine suppression treatment is not well-established as atrial arrhythmias. 3 Therefore, the main objective of our study was to focus on electrocardiographic indicators, which primarily indicate ventricular arrhythmias. In this context, QT dispersion was not one of our study’s mainly evaluated electrographic parameters. When we looked at the literature, we saw that a recent study has reported levothyroxine suppression treatment affects QT dispersion in patients with differentiated thyroid cancer. 4 Evaluating QT dispersion in our study population may be a subject of new research.
The other question of Yayla et al 1 was the surgical success of the patients in our study. However, our study 2 was not designed to compare presurgical and postsurgical electrocardiography. We aimed to compare electrocardiographic changes between postsurgical patients already under levothyroxine suppression treatment and healthy controls. So, we cannot comment on the surgical success of the operated patients.
The two topics mentioned above may be investigated in further research.
