14. Use of bicycle ergometry and sustained handgrip exercise in the diagnosis of presence and extent of coronary heart disease.

15. Exercise testing and training in patients with peripheral vascular disease and lower extremity amputation.
Patients with peripheral vascular disease have a high risk of coronary artery disease. The risk is even greater when the peripheral vascular disease leads to lower extremity amputation. Exercise testing using lower extremity exercise has been the "gold standard" for screening for coronary artery disease, but many patients with peripheral vascular disease and

16. Reduction of mismatch of global ventilation and perfusion on exercise is related to exercise capacity in chronic heart failure.
BACKGROUND--The inability to match lung perfusion to ventilation because of a reduced cardiac output on exercise contributes to reduced exercise capacity in chronic heart failure. OBJECTIVE--To quantify ventilation to perfusion matching at rest and at peak exercise in patients with chronic heart failure and relate this to haemodynamic and ventilatory variabl

17. Contribution of peripheral chemoreceptors to ventilation and the effects of their suppression on exercise tolerance in chronic heart failure.
OBJECTIVES: To assess the contribution of peripheral chemoreceptors to ventilation and the effects of continuous inspired oxygen on exercise tolerance in chronic heart failure patients. The role of peripheral chemoreceptors in mediating hyperpnoea in chronic heart failure is unknown. Hyperoxia is known to suppress the peripheral chemoreceptor drive. The magn

18. Coital cephalgia and ischaemic muscular work of the lower limbs.
A case is reported of a patient who presented with coital cephalgia, and in whom an obstructive lesion of the lower aorta was demonstrated. Bicycle ergometry evoked an abnormal pressor response. The condition was cured by restoration of normal circulation. An abnormal pressor response to treadmill exercise was shown to exist in subjects with intermittent cla

19. Nifedipine in the treatment of myotonia in myotonic dystrophy.
Abnormal calcium transport may be implicated in the membrane defect in myotonic dystrophy. A single blind crossover trial of placebo (t.i.d.), nifedipine 10 mg (t.i.d.) and nifedipine 20 mg (t.i.d.), was performed in 10 patients with myotonic dystrophy. The severity of myotonia was assessed by measuring finger extension time after maximum voluntary finger fl

20. Effect of exercise on cycle length in atrial flutter.
OBJECTIVE--To examine the effect of exercise on cycle length in atrial flutter. PATIENTS--15 patients with chronic atrial flutter. Seven patients were taking digoxin and six verapamil; two were not taking medication. METHODS--All patients underwent bicycle ergometry. Flutter cycle length was measured at rest and at peak exercise. RESULTS--Mean flutter cycle

21. Dose response study of ipratropium bromide aerosol on maximum exercise performance in stable patients with chronic obstructive pulmonary disease.
BACKGROUND: Although the bronchodilating effect of inhaled anticholinergics has been established in patients with chronic obstructive pulmonary disease (COPD), their effects on exercise capacity are still controversial. Previous studies have suggested that the standard dosage hardly affects exercise tolerance, whereas higher doses might elicit an improvement

22. Assessing cardiac pumping capability by exercise testing and inotropic stimulation.
In heart failure both functional capacity and prognosis are primarily determined by the degree of pump dysfunction. Although data on haemodynamic function at rest may indicate impaired cardiac function, they do not assess the capacity of the heart to respond to stress. Maximal bicycle ergometry and incremental intravenous inotropic stimulation in 31 patients

23. A comparison of methods of analysing exercise tests for diagnosis of coronary artery disease.
The diagnostic accuracy of the following methods of analysing exercise tests were evaluated: (a) the cumulative area of ST segment depression during exercise normalised for workload and heart rate (exercise score); (b) discriminant analysis of electrocardiographic exercise variables, workload, and symptoms; and (c) ST segment amplitude changes during exercis

24. Evidence for cardiovascular autonomic nerve dysfunction in multiple sclerosis.
In 21 patients with multiple sclerosis and 20 healthy controls, the following tests of autonomic function were examined: (1) variation in heart rate during deep breathing, (2) the variations in heart rate and systolic blood pressure during a standardised Valsalva manoeuvre, (3) the changes in heart rate and systolic blood pressure during arm ergometry starti
