1. An arrangement (10) for monitoring and adjusting a control of an electromedical implant (12) for intracardial cardiac therapy by means of an external control and evaluation unit (14) in which (a) the electromedical implant (12) includes the following components:

  • a clock and timer unit (40) for the co-ordination of a time sequence of control operations, an energy source for providing an operating voltage and stimulation and shock delivery, at least one electrode (38) which is connected to the myocardium of the heart and which is suitable for the delivery of electrical pulses, a sensor means (28) which supplies measurement data about physiological parameters in the region of the heart and about internal status parameters of the implant, a memory unit (34) for the storage of internal control sequences (SSin), control parameters (SP) and measurement data of the sensor means (28), a telemetry unit (16) having a transmitter (24) and a receiver (20) for bidirectional data exchange with the external control and evaluation unit (14), and a central, autarchically runnable control logic means (30) which on the basis of the internal control sequences (SSin) and control parameters (SP) controls the activities of the at least one electrode (28), the telemetry unit (16), the sensor means (28) and the memory unit (34), and (b) the external control and evaluation unit (14) includes the following components;

    a telemetry unit (18) having a transmitter (22) and a receiver (26) for bidirectional data exchange with the electromedical implant (12), a clock and timer unit (42) for the co-ordination of a time sequence of control operations, an energy source for providing an operating voltage, a memory unit (36) for storing control sequences (SS), control parameters (SP) and communicated data (Dim) of the implant (12), and a central, autarchically runnable evaluation logic means (32) which controls the activities of the telemetry unit (18) and the memory unit (36), which is connected to the clock and timer unit (42) and which on the basis of the communicated data (Dim) ascertains control sequences and control parameters (SS, SP) for monitoring and adjusting the implant (12) and co-ordinates the transmission thereof to the implant (12).
