ABSTRACT
Ruptured chordae tendinae of the tricuspid valve is exceptional. It results in an intense valvular incompetence through systolic eversion of one leaflet. In fact, this is not always the case, and in patient reported, the clinical picture suggested an obstacle to right ventricular ejection with paroxysmal phenomena of the faintness type, indicating the temporary obstruction of the pulmonary pathway. Right cine-angiocardiography demonstrated a mobile intraventricular neoformationreaching in systole the pulmonary sub-valvar area. No tumour was found on operation. The patient died in the post-operative period. On post-mortem examination there was a rupture of tricuspid chordae tendinae and a raise of the anterior leaflet of the tricuspid valve into the pulmonary infundibulum. Rupture could be related to a severe thoracic trauma which had occurred 17 years previously.

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.

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.
