title: [Extemporaneous analysis of myocardial performance by a programmable automatic dynamometer].
abstract: This article describes a biophysical investigation to determine the physiological integrity of isolated cardiac fibers obtained during surgery. Immediate biopsy of myocardium can be analysed dynamically in various physiological conditions using an intelligent dynamometer controlled by an "APPLE II" microcomputer generally in less than fifteen minutes. Multiple tests including pharmacological and electrical properties of fibers can now be done with this cardiac analyser. Primary investigations on heart diseases show the importance of the method for evaluation of heart necrosis.
