Both drugs exhibited almost equal antihypertensive response, and were well tolerated. Haemodynamic variables (HR, SBP, DBP and RPP), both at rest and after maximal tread mill exercise, were significantly altered (P less than 0.001) by both drugs. Exercise capacity was observed to be marginally improved by atenolol. Although the antihypertensive effect, when compared between the two drugs, was not statistically significant, individual suitability or comparison revealed a preference for atenolol in 17 patients and for labetalol in 3 patients.Item Devic's disease. A case report.(1973-04-01) Agrawal, S P; Bahl, L; Tewari, G N; Srivastava, S CItem Direct-reading normograms for systolic time intervals (S.T.I.).(1980-07-01) Srivastava, S C; Gupta, R RItem Effect of blood transfusion upon myocardial contractile function in chronic severe anaemia--a study of systolic time intervals (STIs).(1983-03-01) Gupta, R R; Srivastava, S CItem Electrocardiographic study in the newborn.(1969-12-01) Prasad, R; Mathur, K S; Dayal, R S; Krishore, N; Srivastava, S C; Thapar, R KItem An electrocardiographic study of myocarditis in diphtheria.(1966-06-01) Srivastava, S C; Puri, D S; Lumba, S PItem Gastric changes in non-ulcer dyspepsia.(1978-05-01) Khosla, S N; Chugh, S N; Mehrotra, G C; Srivastava, S C; Jain, A LItem Hepatopulmonary amoebiasis.(1991-09-01) Srivastava, S CItem Interpretation of treadmill stress test in patients with coronary artery disease receiving beta blocker therapy.(1991-02-01) Srivastava, S C; Katyal, V K; Jagdish,; Gupta, S; Mohan, RGraded maximal treadmill exercise responses were studied before and after beta blockade (atenolol 100 mg once daily for 2 weeks) in 20 male patients with chronic stable angina. Beta-blocking effect consisted of significant reduction of resting heart rate (HR) by 21%, systolic blood pressure (SBP) by 12% and rate pressure product (RPP) by 30%. While the maximum exercise capacity was marginally increased by mean 1.7 min +/- 1.6 SD (P less than 0.001) under the influence of therapy, peak HR, SBP and maximum RPP were significantly lower (P less than 0.001) than in preatenolol exercise tests. Similarly, while the configuration and magnitude of ST segment depression did not differ materially between the pre and post atenolol tests, onset time of ST change was delayed and offset time shortened significantly. These parameters cannot be relied upon to assess the extent and severity of coronary artery disease (CAD) if stress test is carried out while the patient is on a beta-blocking drug. The overall sensitivity of the stress test to detect coronary disease is, however, not likely to be compromised because of negligible influence of beta-blockers upon ST segment depression provided maximally tolerated (not submaximal) exercise is performed. ST/HR slope, an exercise test variable known to correlate well with the extent of CAD, was shown to be uninfluenced by beta-blockade. Its measurement is therefore recommended in interpreting stress tests performed in patients receiving beta-blocker therapy. This, however, requires a meticulously prepared protocol of recording computer averaged QRST complexes and multilead ECG tracings at very frequent intervals throughout the exercise.(ABSTRACT TRUNCATED AT 250 WORDS)Item Left ventricular performance in hypertension: a study of systolic time intervals.(1979-11-01) Srivastava, S C; Siwach, S B; Singh, N; Popli, H CItem Normal values and regression equations of systolic time intervals.(1979-07-01) Srivastava, S C; Gupta, R R; Popli, H CItem Peak expiratory flow rate and its prediction formulae in Haryanvis.(1984-10-01) Mahajan, K K; Mahajan, S K; Maini, B K; Srivastava, S CPeak expiratory flow rate (PEFR) was studied in 806 healthy 6 to 58 year old Haryanvi males. A steep rise in PEFR is seen with age up to 18 years, little variation occurs between 19 to 26 years and is followed by a gradual fall thereafter. The formulae for the prediction of PEFR from age and height in different age groups have been worked out. Haryanvi children are taller having PEFR and predicted values of PEFR higher than the children of other Indian states and are well comparable to Western children. On the other hand in Haryanvi adults observed and predicted values of PEFR are low. It is possible that economical uplift of this area due to industrialization and green revolution has led to improved nutrition resulting into better physical and functional (PEFR) development of younger generation. It is suggested that in developing states the physical and functional norms should be periodically reviewed.Item Pulmonary functions and their correlation with anthropomorphic parameters in young adults of Haryana (India).(1978-01-01) Mahajan, K K; Maini, B K; Mahajan, S K; Srivastava, S C; Chander, SPulmonary functions in 169 young males of Haryana were studied with the help of a water seal spirometer and Wright's peak flow meter. Different parameters analysed were FVC, FEV1%, P.F.R., MVV, and expiratory flow rates between 25-50%, 25-75% and 50-75% of FVC. Our mean values are well comparable with those of Indian workers but less than those reported by Western workers. Pulmonary functions correlate better with physical parameters, height arm span and upper segment than with age. Correlation coefficient (r) values of FVC and anthropomorphic parameters are +0.7953, +0.3835, +0.3566 and +0.0992 with arm span, upper segment, height and age respectively. These values of pulmonary functions in healthy adults when compared with those obtained from patients suffering from chronic obstructive lung disease, it was observed that expiratory flow rates may be more useful in the detection of pulmonary changes in obstructive lung diseases at an early and reversible stage.Item Single oblique chest lead electrocardiogram.
