Major adaptations occur in the maternal cardiovascular system during normal pregnancy and knowledge of these changes is essential to the management of women with cardiovascular disease. The present study was designed to assess heart rate and blood pressure variations in the three trimesters of pregnancy. 100 subjects in age-group of 20-40 years were taken up for the study, of these 75 were healthy pregnant females further divided into three groups of 25 each according to the trimesters of pregnancy and remaining 25 were non-pregnant healthy females (control). The variations in blood pressure (both systolic and diastolic) and heart rate were studied in first, second and third trimesters of pregnancy as well as in non-pregnant healthy females. The study showed significant increase in heart rate in the third trimester compared to non-pregnant healthy females (p0.05).
