Dual chamber cardiac pacemakers restoring an impaired atrioventricular synchrony meet a demand of contemporary so-called physiologic cardiac pacing. 39 dual chamber (DDD) pacers were implanted in 1982-1991 in our center. They improved both well-being and hemodynamic values (doppler echocardiography) more distinctly than common ventricular demand devices did. P-wave driven ventricular pacing in normal sinus node function (in 40 per cent of our DDD patients) made a frequency response in physical exercise possible. A short atrioventricular delay in DDD pacing proved to be helpful in the treatment for reentry tachycardias refractory to antiarrhythmic drug administration. Demanding implant, high price, lengthy programming as well as a higher incidence of complications (30.7 per cent) as compared to ventricular pacemakers (7.6 per cent) were the main problems of DDD ones.
