Obesity is
associated with wide variety of electrocardiographic (ECG) abnormalities.
Prolonged QTc interval is common in obesity and it represents a delayed
ventricular repolarisation which is associated with ventricular arrhythmias, syncope
and sudden cardiac death.
The aim of our
study is to evaluate the effects of weight reduction on QTc interval in obese
subjects. The study included 74 obese subjects aged 41.78 ± 10.70 years,
treated with a lowcalorie diet (800 kcal/day) for two weeks.
All patients
underwent a standard resting 12-lead surface ECG before and after the
treatment. QTc intervals were corrected by Bazett’s formula. Results: The
average loss in body weight was 10.26 ± 3.63%, and the average reduction in
body mass index was 9.39 ± 4.23%.
