A transducer (4) for measuring movements of the myocardium and the electrical signals generated by those movements comprises a multi-element strain gauge (9) combined with electrodes, and is retained on the myocardium by suction, thus avoiding intrusion into the myocardium and consequent trauma. Strain gauges (9) for measuring axial and radial strain are attached to each of three legs (2) and vacuum lines (1) and conductors (13) extend down the legs to orifices and electrodes respectively on the bottom of rubber feet (3).
