Responses to a multistage treadmill test of maximal exercise were studied in 61 hypertensive patients: 13 had uncomplicated hypertension; 15 had associated retinopathy; 22 had left ventricular hypertrophy; and 11 also had coronary heart disease. Because of significant differences with aging normally, and differences in ages of these subgroups, responses were compared with those of normotensive ...

BACKGROUND To compare the prognostic value of estimated glomerular filtration rate, cystatin-C, an alternative renal biomarker, and their combination, in an outpatient population with heart failure. Estimated glomerular filtration rate is routinely used to assess renal function in heart failure patients. We recently demonstrated that the Cockroft-Gault formula is the best among the most commonl...

BACKGROUND Our aim was to evaluate electrocardiographic and echocardiographic properties and exercise response of patients with fibromyalgia (FM). METHODS The study included 60 women with primary FM and 30 healthy individuals. Resting electrocardiography, echocardiography and exercise treadmill test were used to compare these two groups. At apical four-chamber window, samples of transmitral d...

These electrocardiograms were taken on a 36 yearold man, with no known cardiac abnormality. The twelve-lead tracing, which shows sinus rhythm at rates between 53 and 60/min., has abnormal T waves in Vl V4. A s{rip, using lead V6, shows the interesting phenomenon of rate-dependent left bundle branch block (LBBB). Please. note in this strip that the first four sinus beats have normal QRS-T waves....

AGE ASSOCIATED DECLINES IN EXERCISE TIME TO EXHAUSTION AND VENTILATORY PARAMETERS IN TRAINED CYCLISTS. Frank B. Wyatt, Jason P. Mccarthy. JEPonline. 2002;6(1):1217. The purpose of this study was to investigate the cardiopulmonary parameters in a cross section of fit, aging cyclists to determine the associations between age, heart rate and ventilation on exercise time to exhaustion. Subjects wer...

INTRODUCTION Oral amiodarone has been suggested by some authors for rate control in patients with persistent atrial fibrillation. In this study we evaluated the efficacy and safety of oral amiodarone versus placebo for rate control during exercise and daily activities in patients with chronic atrial fibrillation who had undergone digitalisation. METHODS The study group consisted of 53 patient...

a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...

objective: for many years in herbal medicine the antihypertensive and lowering blood lipid properties of achillea wilhelmsii (a. wilhelmsii) have been suggested. in the present study the impacts of the plant extract on rabbit’s blood pressure and heart rate have been investigated. materials and methods: twelve nwz rabbits weighed 2-3 kg were randomly divided into two groups of 6 rabbits. the te...

background: at the present time, massage has become a popular therapy employed in complementary medicine. there is evidence showing that back massage might have many positive psychological effects, possibly due to having many autonomic nervous system afferent inputs. one of the frequent positions during massage is prone position. however, there has been limited research investigating the effect...

conclusions the mean heart rate was higher in participants who were overweight than those with normal weight. results the mean and standard deviation of the heart rate in the hot climatic condition and moderate exercise were 103.84 (3.34) for normal weight subjects and 108.67 (3.27) for overweight subjects. the mean and standard deviation of the heart rate in a very hot climatic condition and l...
