Investigation of Dysynchrony in Patients With Pulmonary Hypertension

The purpose of the study is to determine whether patients with pulmonary hypertension (PH) have dysynchrony, and if so whether it is electrical or mechanical. Once this has been determined, during a catheterization the investigators will test if pacing the heart improves blood circulation.

Stanford is currently accepting patients for this trial.
