Previous studies have demonstrated impaired ventricular repolarization in patients with β-TM.
However, the effect of iron overload with cardiac T2* magnetic resonance imaging (MRI) on cardiac repolarization remains unclear yet.
We aimed to examine relationship between repolarization parameters and iron loading using cardiac T2* MRI in asymptomatic β-TM patients.
Twenty-two β-TM patients and 22 age- and gender-matched healthy controls were enrolled to the study.
From the 12-lead surface electrocardiography, regional and transmyocardial repolarization parameters were evaluated manually by two experienced cardiologists.
All patients were also undergone MRI for cardiac T2* evaluation.
Cardiac T2* score <20 msec was considered as iron overload status.
Of the QT parameters, QT duration, corrected QT interval, and QT peak duration were significantly longer in the β-TM group compared to the healthy controls.
Tp−Te and Tp−Te dispersions were also significantly prolonged in β-TM group compared to healthy controls.
(Tp-Te)/QT was similar between groups.
There was no correlation between repolarization parameters and cardiac T2* MRI values.
In conclusion, although repolarization parameters were prolonged in asymptomatic β-TM patients compared with control, we could not find any relation between ECG findings and cardiac iron load.
