Abstract

India has highest prevalence of nutritional anaemia. Its prevalence is high in women & children. Anaemia results in tissue hypoxia. In anaemia as Hb concentration & RBC count decrease it causes hyperdynamic circulation leading to tachycardia. The abnormalities found in ECG were due to myocardial hypoxia resulting from decreased oxygen carrying capacity of the blood. To overcome myocardial hypoxia various hemodynamic & non hemodynamic mechanisms come to play a role to compensate for anaemia. But in the long term, hemodynamic alterations lead to gradual development of cardiac enlargement & ventricular hypertrophy. So if anaemia remains untreated it may lead to cardiac complications which lead to poor prognosis. This is the reason to study the effect of anaemia on ECG. The subjects for study were 75 men & women. Severity of anaemia was decided by Hb concentration. Study cases were divided according to comparision of severity of anaemia with: ECG changes, age group & ECG changes & type of ECG abnormality. In our study we found abnormality in ST segment & T wave. In this study, we have tried to summarize the effects of anaemia on ECG.
