The use of a pacemaker has been advocated in a subset of individuals, in order to cause asynchronous contraction of the left ventricle. Since the pacemaker activates the interventricular septum before the left ventricular free wall, the gradient across the left ventricular outflow tract may decrease. The AV interval must be shortened to do this, but not at the expense of diastolic filling. This form of treatment has been shown to provide less relief of symptoms and less of a reduction in the left ventricular outflow tract gradient when compared to surgical myectomy
. Dual chamber<unk>  does not decrease the risk of sudden cardiac death in these patients.
