ECG Changes in Obese Individuals

Abstract

The electrocardiogram in 100 subjects was correlated with the severity of obesity. QRS vector shifted to the left with increasing obesity in 42%of people which indicates left ventricular hypertrophy. These changes were independent of age, sex and blood pressuire. Interventricular conduction defect was present in 21% of patients, but t wave inversion was in 14% only. 17% of people had normal ECG, whereas 3% of have showed sinus bradycardia & arrhythmia. The shift of QRS vector to the left and the conduction abnormalities are increasing with increase in obesity. Since theleft ventricular hypertrophyis an important risk factor for sudden cardiac arrest, this non-invasive procedure may be utilized as a routine screening test for obese people for better medical care. Thus, obesity is associated with a wide variety of ECG abnormalities, many of which are corrected by weight loss.

Electrocardiogram of Obese Young Adults in a University, Malaysia

“…In the previous studies, it was found that increase in LV wall thickness, LV mass and prevalence of echocardiographic LV hypertrophy are associated with obesity but not related to blood pressures (Karthikkeyan, Umadevi, and Gajapriya, 2016). It is agreed in this study according to the findings of systolic blood pressure, R wave and S waves.…”

“…These hypervolemic and hyper dynamic status increases left ventricular work and lead to an increase in cardiac mass that is proportional to degree of obesity. Increased cardiac mass is due to increased muscle mass of left ventricle and not due to epicardial or myocardial fat infiltration (Karthikkeyan, Umadevi and Gajapriya, 2016).…”
