Action of norepinephrine on the serum gastrin level.

The authors have studied the influence of endogenous norepinephrine released during exercise on the level of serum gastrin. After a period of absolute rest, 10 volunteers in good health underwent a prolonged graded exercise corresponding to 60, then 80% of the maximum theoretical heart-beat frequency. Only norepinephrine was significantly high during the course of the second phase of muscular activity. No significant change in serum gastrin was observed during the entire test.

[Reproducibility of measurements of arterial pressure and heart rate during exercise test: its significance and application].

The authors report their findings from a study of the reproductibility of measurements of blood pressure and heart rate both at rest and during exercise (work on a bicycle ergometer) in 19 patients who were tested on two occasions with a mean interval of 9.8 days. A study of the correlations, of variability, and of the findings on applying Student's "t" test, have led us to the conclusion that these parameters are more reproduceable on exercise than at rest, and become increasingly reproduceable as exercise increases. These conclusions support the use of an induced hypertension test under exercise.

[Data from systematic electrocardiographic study during exercise in hypertensive patients. Apropos of 307 cases].

The authors report the data of a systematic electrocardiographic study of 307 subjects suffering from hypertension. They analyse the EKG anomalies at rest and after exercise and study the relationships likely to exist between these anomalies and other parameters such as age, blood pressure, etc. They stress the diagnostic but also discriminatory value of this type of investigation in hypertension.

[Test of provoked arterial hypertension. Value and limitations of the static exercise of prolonged handgrip].

The used of a test of prolonged grip and recording the changes in arterial blood-pressure and heart rate is suggested as a way of studing the blood-pressure changes of effort in hypertensives. This test provides a real screen for provoqued hypertension: it allows --to define a normal profile of reference for blood-pressure, --to check the fluctuations at rest of blood-pressure, --to determine the severity of haemodynamic dissorders, --to judge the efficiency of hypotensive therapy.

[Value of the study of the arterial pressure values under exercise in normotensive and hypertensive patients].

Study of the blood pressure and cardiac rate changes in the course of an exercise test makes it possible to assess the possibilities of cardiovascular adaptation. This "induced arterial hyperrtensive subjects from those who possibly are not, and to assess correctly the blood pressure changes observed in various circumstances. On effort, an approach of the severity of the haemodynamic disturbance of the consequences of this disturbance, of the efficiency of treatment.
