[Acute phase of ventricular fibrillation in myocardial infarct. Importance of studying electrical systole by determining the QTc].

Recent reports have drawn attention to the association between long QT intervals and sudden death in myocardial infarction and certain congenital syndromes. This study was undertaken to determine the relationship between lengthening of the QT interval and primary ventricular fibrillation in acute myocardial infarction. Thirteen cases were chosen out of a total of 21 cases of primary ventricular fibrillation (5.09% of 412 cases of myocardial infarction hospitalised during this period). Ten other cases of myocardial infarction with the same features apart from the arrhythmia were used as controls. Three series of electrocardiogrammes recorded under the same technical and chronological conditions (2 before and 1 after ventricular fibrillation) were analysed. The average QT interval was corrected for heart rate (RR) with Bazett's formula. The average QTc in acute myocardial infarction was longer than the theoretical QTc (p less than 0.05). The graph showing this increase reached a peak at the 48th hour. The average QTc in patients with primary ventricular fibrillation was longer than in the control patients (p less than 0.05) and significantly longer than the theoretical value (p less than 0.001). The average QTc in survivors of ventricular fibrillation was not significantly longer than that of the control group but was longer than the theoretical value (p less than 0.01). These results justify the strict surveillance of the length of electrical systole in the first hours of the acute phase of myocardial infarction. In this series, values greater than 440 ms were associated with a high risk of ventricular fibrillation in the first week after myocardial infarction.

Prolonged electrical systole in acute myocardial infarction.

Electrical systole duration has been studied in two groups of 23 patients (39 M and 7 F) admitted in the coronary care units of two different hospitals for documented acute myocardial infarction (AMI). The mean QT interval duration corrected for heart rate (QTc) was obtained from three measurements of non consecutive complexes in five different leads and compared to the ideal electrical systole duration of a normal population with the same cardiac cycle length. During the evolution of AMI, QT interval increased in both groups of patients (11.5% and 14.8% respectively) and was prolonged (17.6% and 21.5% respectively) at the 48th hour. Prolongation of electrical systole can be best measured using the ratio: QTc (according to Bazett)/normal QT (according to Ashman).

[Subclavian route placement of electrodes for permanent stimulation].

The subclavian vein gives a rapid, direct approach to the right heart cavities. The pacing catheter was introduced via the subclavian vein in a series of 187 patients. A no. 9 Desilets and Hoffman percutaneous catheter introducer may be used with most types of pacing catheter, including bipolar models. Complications were rare : one case of pneumothorax was observed. The subclavian vein approach simplified the operative procedure of implantation and offers a useful alternative in difficult cases of reimplantation.

Results of a national therapeutic trial conducted in 10,000 hypertensive patients by 2000 general practitioners.

1. 10,294 hypertensive patients were treated and followed by 2200 general practitioners under the supervision of 130 cardiologists and nephrologists. 2. The treatment groups, randomly allocated, were designated to use three distinct antihypertensive drugs, administered alone, and combined two-by-two. 3. Some 75% of patients had a supine diastolic blood pressure of less than 95 mmHg after 4 months treatment. 4. A total of 12% of patients had dropped out by 4 months from entry; no clear relationship was established between side effects and drop out.

[A rare cause of continuous thoracic murmur. A fistula between the internal mammary artery and the pulmonary circulation].

The authors present a case of a continuous right lateral sternal murmur which led to the discovery of a systemic-to-pulmonary fistula at the origin of the internal mammary artery. The fact that the patient had a right pulmonary abscess with pyopneumothorax drained several years previously has led them to discuss the possible etiology of this fistula. The murmur disappeared after surgical treatment.

[Application of echocardiography to the diagnosis of tricuspid valve diseases. Apropos of 103 cases].

In a series of 103 consecutive surgical patients, the normal and pathological echocardiographic appearances of the tricuspid valve were analysed and compared with the anatomical findings. It was possible to define the nature of the lesions by echocardiography, which was superior to angiography in this field. The right ventricular index (right ventricular dimension body surface area) correlated well with the mean pulmonary artery pressure (r = 0.75; p less than 0.001). The index may be useful in the long term follow-up of post-operative patients.

[Pluri-dimensional study of psychological factors in coronary disease].

To palliate certain criticisms levelled at workers studying psychological factors in coronary artery disease, the authors have applied a pluri-dimensional approach associating a semi-direct psychological interview, a self-evaluation test (Bortner scale), an Eysenck personality test and Sandler and Hazari's test of obsessional behaviour. This protocol was applied to 222 patients hospitalised for coronary artery disease and 522 random controls. The psychological interview and Bortner test showed a significantly higher proportion of A pattern and especially extreme A pattern behaviour in patients with coronary artery disease (32.6 % in coronary patients 9.7 % in controls). The personality questionnaire showed a greater tendency to neurotic behaviour in the coronary patients. These results were independant of age and sex. In the present study, psychological factors are given equal importance to other major risk factors (tobacco, hypertension, hypercholesterolaemia). They are independant of these other factors. A prospective study using the same protocol is being prepared.
