Pacemaker Therapy for Drug-refractory Symptoms in Mid-cavity Hypertrophic Cardiomyopathy

Ventricular pacing via the invasive haemodynamic study-defined optimal pacing site in order to relieve pressure gradient across the mid-cavity obstruction in mid-cavity obstructive variant hypertrophic cardiomyopathy.

Back-up pacing. The pacemaker is set-up to sense and pace only in the right atrium (AAI) without any pacing capacity in the ventricle.
