[A programmed universal stimulator for the diagnosis and therapy of bradycardial and tachycardial arrhythmias].

Special kinds of electrostimulation, particularly the so-called programmed stimulation, are necessary for the specialised diagnostics of disturbances of nervous impulses of the heart and of the conduction system with intracardiac ECG (His-electrocardiography). A pacemaker using constituents of microelectronics is described which apart from fixed frequent, coupled, P/R-linked, bifocal and higher frequent atrial stimulation makes possible a programmed stimulation according to a preelected programme. Apart from the use for diagnostics the stimulator is suited for the therapy of bradycardic disturbances of the rhythm and for the termination of tachycardias.
