Right bundle branch block: a source of error in the Doppler assessment of right ventricular pressure in patients with a ventricular septal defect

A case is presented in which low right ventricular pressure was calculated erroneously from the Doppler-derived velocity of flow through a ventricular septal defect. This is thought to be due to the presence of right bundle branch block. Reasons for this error and a way to avoid errors in calculatio...

Summary:A case is presented in which low right ventricular pressure was calculated erroneously from the Doppler-derived velocity of flow through a ventricular septal defect. This is thought to be due to the presence of right bundle branch block. Reasons for this error and a way to avoid errors in calculation are discussed.
