title: Acute pulmonary hypertension secondary to right ventricular pacing in a patient with sinus node dysfunction and severe ischemic cardiomyopathy.

We describe a patient with severe ischemic cardiomyopathy and sinus node dysfunction who developed acute worsening of pulmonary hypertension immediately after right ventricular pacing.
