title: [Diagnostic significance of phono-mechanographic medication of constrictive endocardial fibrosis (or endomyocardial fibrosis)].
abstract: The phonomecanographic investigation of 12 patients with FEC allow us to recognize diagnostics signs of great interest. 1. The ventricular aspect of the jugular veinous pulse involving a positive systolic wave and a diastolic aspect in "dip-plateau" is a chief indication of a right ventricular fibrosis. This indication is more significant of FEC when the nadir of the dip is far above the base line, when the dip-rising time is short, when the telediastolic ratio is high (more important than 0.40) when the electro-mechanical latency time is prolonged and when the isovolumetric relaxation time is normal. 2. The apexogram aspect in diastolic dip-plateau is a capital indication for a fibrosis of the left ventricule. This indication is more significant when the nadir of the dip is above the baseline, when the telediastolic ratio is high (more important than 0.30) when the electromechanical latency time and the isovolumetric relaxation time are normal. 3. The protodiastolic endocardial vibrancy recorded during the dip climbing and showing the features we described, seems to us to be a very important sign. This vibrancy can be preceded or/and followed by a short and early diastolic murmur of low frequency, always finishing at the end of the dip. 4. Recording of pulmonary valves or atrio-ventricular murmur is an important diagnostic feature in an adiastolic syndrome. 5. Recording of a pulmoanry infundibular impulse is an indication for a right ventricular fibrosis. This indication is very significant if the tracing is a dip-plateau.
