[Mitral valve prolapse and spasmophilia in the adult].

75 cases of mitral valve prolapse (MVP) for which no cause was found underwent electromyography (EMG). In 64 cases (85.3%) EMG showed changes suggestive of spasmophilia. The symptoms observed were those already described in this condition. The specific clinical signs of spasmophilia were often elicited with a positive Chvostek sign in 20 out of 30 cases (73.3%). Radiological, echocardiographical and haemodynamic studies underlined the hyperkinetic state of the left ventricle. Biochemical investigations showed a high incidence of low erythrocytic magnesium levels. Chest pain suggestive of angina pectoris, mitral valve prolapse and spasmophilia are frequently associated. The role of the low erythrocyte magnesium on left ventricular hyperkinesis and the production of MVP is discussed.

[Coronary insufficiency in the female: possible effect of menopause].

A population of 239 women suffering from chronic coronary disease was divided into two groups according to whether or not they had sustained a myocardial infarction. For the 226 post-menopausal women, the type of menopause (natural or artificial) and their age at its onset were determined, together with the age of onset of the infarction or angina, and possible correlations with other risk factors in atherosclerosis. Whilst the average age at the time of artificial menopause was markedly less than that of natural menopause, the age of onset of coronary complications was comparable regardless of the type of menopause, this applying to both groups. Contrary to a classically accepted opinion, early menopause would not appear to favourise the premature development of atherosclerotic coronary problems, and, in addition, would not appear to affect other coronary "risk factors".

[Electrophysiologic study of fenoxedil chlorhydrate].

Electrophysiologic studies were carried out on 10 patients before and during therapy by Fenoxedil Chlorhydrate a new anti-arrhythmic drug, to determine the effects on cardiac conduction. Fenoxedil Chlorhydrate produces a constant alteration of intra-nodal conduction. Modification of sinus function are less evident. Auricular and ventricular refractory periods are increased in the majority of cases. These results give a better understanding of mecanism of this drug, and helps in its prescription in clinical practice.

[Treatment of rhythm disorders by fenoxedil hydrochloride].

Fenoxedil chlorhydrate (FC), which is used as a treatment for cerebral circulatory failure and peripheral vascular disease, has been given to 100 patients with a cardiac arrhythmia: atrial fibrillation (78 cases), atrial flutter (4 cases), atrial tachysystole (2 cases), ventricular extrasystoles (12 cases), and supraventricular extrasystoles (4 cases). FC has been prescribed alone, or as a complement to current anticoagulant or digitalis treatment; combination with prenylamine, amiodarone, dysopyramide or a drug of the quinidine group must always be avoided, and the potassium level checked and corrected if necessary before treatment. In 78 cases of atrial fibrillation, the authors found that sinus rhythm was restored in 58 (74.4%); four cases of flutter were restored, and one case out of two of atrial tachycardia. In case of supraventricular and ventricular extrasystoles the results are less clear, and merit a further study with a larger number of cases. The electrocardiographic disorders encountered in this series have been evaluated: lenghthening of the QT interval, disorders of atrioventricular conduction, sinus inhibition. They were either produced by or aggravated by the FC. No cases of axis deviation were encountered. The authors make mention of the complications observed by other authors, but draw a distinction between the prescription of FC in cases of cerebral vascular insufficiency, without previous knowledge of the exact cardiac status of the patient (otherwise there is a risk of severe accidents), and the use of FC in cases of arrhythmia which have undergone full assessment before the drug is used. According to this study, FC appears to be a very effective anti-arrhythmic agent, but its use demands very rigorous clinical and electrocardiographic supervision.

["Habitual" left branch block alternating with 2 "disguised" bracnch block].

Two cases of alternating left bundle branch block and "masquerading block" (with left bundle branch morphology in the stnadard leads and right bundle branch block morphology in the precordial leads) were studied by serial tracings and his bundle electrocardiography. In case 1 "the masquerading" block was associated with a first degree AV block related to a prolongation of HV interval. This case is to our knowledge the first cas of alternating bundle branch block in which his bundle activity was recorded in man. In case 2, the patient had atrial fibrilation and His bundle recordings were performed while differents degrees of left bundle branch block were present: The mechanism of the alternation and the concept of "masquerading" block are discussed. It is suggested that this type of block represents a right bundle branch block associated with severe lesions of the "left system".

Erythrocyte 2,3-diphosphoglycerate as related to diabetes and obesity.

2,3-Diphosphoglycerate was determined in the erythrocytes of 17 diabetic and 18 obese patients. Results for obese subjects were significantly (P less than .01) different from those obtained for 21 healthy subjects. Results for obese and diabetic patients also differed significantly (P less than .01) but not those for diabetic and healthy subjects. Hemoglobin, hematocrit, or bicarbonate measurements did not differ among the three groups.

[Propranolol and arterial hypertension: study with frequent daily checking of blood pressure and serum levels after 1 week of treatment].

In order to establish correlations between serum levels of Propranolol, blood pressure in hypertensive patients and cardiac rate, these parameters have been recorded at three different times in a day and after a week. This study points out that therapeutic response is variable. However the patients may be classified into 4 groups. This classification and the value of serum levels of propranolol are discussed.
