<p>What is described is an implantable telemetric device for measuring the electromechanical parameters of the heart, characterized in that it comprises a single sensor (5) and corresponding processing means for detecting data relating to both the rotation of the heart and the mechanical vibrations which correspond to the first heart sound (FHS) and the second heart sound (SHS), and in that it comprises means which use these data for diagnostic and/or therapeutic purposes. Said sensor (5) is of the type which can generate a broadband electrical signal proportional to the rotation rate (RotR) of the heart and proportional to said mechanical vibrations corresponding to the heart sounds. Means are provided for processing this RotR signal, for deriving therefrom the functions relating to the rotation of the heart (ˆ«RotRdt) and to mechanical vibrations (d(RotR)/dt) corresponding to the said heart sounds (FHS, SHS) and for detecting data derived from combination of the said functions (e.g. data relating to any time interval (DI) that may be present between the peak of said heart rotation signal (ˆ«RotRdt) and the second heart sound (SHS)) and data derived from basic signal processing operations (i.e. sum, subtraction, multiplication, division, mean, calculation of the area underneath curves) applied to all said functions, and means are provided for using all said data for diagnostic and/or therapeutic and/or monitoring purposes.</p> |
