Cardiostimulation in used less frequently than pharmacotheraphy in the treatment of vasovagal syncope. It proves useful in treatment of vasovagal associated with bradycardia. Cardiostimulati- on of both cavities is more effective than of one cavity. The optimal cardiostimulation algorithm for treatment of vasovagal syncope which ensures an adequate start of cardiostimulation and has an optimal effect on haemodynamic parameters is still sought. The rate drop response algorithm seems promising. This algorithm was used so far only in one randomized study which was to verify the effect of cardiostimulation in the treatment of vasovagal syncope - Vasovagal Pacema- ker Study. The study proved a marked risk reduction of relapses of syncope in highly bradycar- dia during the tilt test. The Vasovagal Pacemaker Study II with is under way at present compares the effect cardiostimulation and placebo and the effect of cardiostimulation with the rate drop response algorithm.
