[Automatic measure of arterial pressure using the oscillometric method (Dynamap 845)].

The reproducibility and reliability of measurements performed with an automatic blood pressure measuring device based on the oscillometric method were assessed by comparison with the results obtained by the indirect auscultation using a mercury manometer. The results of the mean values, of the correlation between successive values and of the variation of the values of systolic and diastolic blood pressure show that the readings obtained by the automatic method are very reproducible.

[Data from a study of variations of arterial pressure during exercise in boys aged 11 to 16].

Systolic, diastolic BP and heart rate were measured in 106 boys aged between 11 and 16 years old, at rest and during exercise on a bicycle ergometer. The results show: -- at rest: an increase in systolic and diastolic BP with age, and a decrease in heart rate; -- during exercise: an increase in systolic BP without an increase, or with a decrease in diastolic BP. The blood pressure readings were higher in overweight and post pubertal subjects. The value of this study lies in the high number of reproducible readings obtained and in the suppression of the effects of emotivity. It completes the observations made at rest in subjects suspected of having hypertension.

[Physiological variations of arterial pressure and heart rate in the first 5 minutes after moving from a supine to an upright position].

The physiological variations of blood pressure and heart rate were studied in the first five minutes of orthostatism in conditions identical to those encountered in clinical medicine. An increase in heart rate and diastolic blood pressure was observed from the first minute. The value of systolic blood pressure decreased as the subject got up and then rose to the value measured when lying down. At the fourth and fifth minute the three parameters were stable at significantly higher values than observed when lying down for the heart rate and diastolic blood pressure, but at an identical level for the systolic blood pressure. This study shows the necessity of measuring the orthostatic blood pressure using a precise technique which detects postural abnormalities when measured in the minute of orthostatism and which gives an assessment of the standing blood pressure when measured at the fifth minute.

[Evaluation of an automatic device for arterial blood pressure determination : the Arteriosonde 1217].

The reproductibility and reliability of measurements made with an automatic device for measuring blood pressure was assessed with reference to the results obtained by indirect auscultation with a mercury manometer. The results of the study of the average values of the correlation between successive values, and of the variability of the values of the systolic and diastolic blood pressure show that the measurement obtained by this method are very reproducible.

[Value of continous 12-hour electrocardiography during the rehabilitation period in patients convalescing from myocardial infarction. Apropos of 40 cases].

The results of continuous 12-hour electrocardiography in 40 convalescent patients after myocardial infarction undergoing a programme of readaptation on average 4 weeks after the initial infarction are reported. The frequency and alarming nature of the VES observed in 75% patients who had already undergone selection for the coronary readaptation programme, 30% of whom were receiving antiarrhythmic therapy, is emphasized. The observation of a progressive increase in the number of VES during the day prompts the following suggestions: the possibility of limited continuous ECG monitoring at the end of the day, the need to adapt the dosage of antiarrhythmic drugs during this most critical period. The comparison of the results of continuous ECG with those of repeated exercise ECG seems very positive, but some reservations are made and it would seem logical to associate these two complementary methods of investigation.

[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.

[Chronic pericardial effusion and congenital cardiopathy].

Report of one case of chronic pericardial effusion combined with pulmonary valve stenosis and atrial septal defect in a man aged 31, hospitalized for congestive heart failure. The relationship between these two diseases were studied, and the diagnostic and therapeutic problems posed were studied.
