Abstract :

Background: Obesity is one of the leading preventable non communicable disease worldover. Obesity is a proinflammatory condition and is a precursor for various diseases like diabetes and hypertension leading to morbidity and mortality. It has significant cardiovascular effects. Of the various electrocardiographic findings in obesity QT interval prolongation may be the precursor of arrhythmias. This may be one cause of sudden cardiac death in obese. The present study intends to find the correlation of obesity with QT interval lengthening. Aims And Objectives: The purpose of this study was to compare the QTc interval of ECG between subjects with normal BMI, overweight and obese in the age group of 18–40 years and to know whether QTc interval varies with the BMI. Materials and method: The study was conducted on 150 subjects at Government Medical College, Amritsar who were graded on the basis of their BMI and there corrected QT interval was calculated from their ECG and their correlation was studied. Summary and conclusion: Normal BMI patients had mean QTc value in the normal range. Of the overweight patients 14% of the patients were found to have QTc in the higher range of the normal but no one had a prolonged QTc. 42% of the obese males and 53% of obese females had a prolonged QTc. Hence QTc interval was positively correlated with obesity. QTc prolongation may be one of the factors leading to an increased incidence of sudden cardiac death in obese.
