[Results of electrical pacing in patients with hypertrophic obstruction cardiomyopathy (author's transl)].

In patients with hypertrophic obstructive cardiomyopathy, left ventricular outflow gradient decreased about 56 per cent by way of electrical stimulation of the apex of the right ventricle. In 4 patients a permanent pacemaker was implanted. P-wave triggered pacemakers with electronic conduction-time of approximately 0 sec showed to be preferable. The decrease of left ventricle outflow gradient as well as of subjective complaints inclusively cerebral syncopes were remarkable.
