Systolic pulmonary and hepatic vein flow reversals can typically be seen with severe atrioventricular (AV) valve regurgitation and during atrial fibrillation (AF). We report the case of a 67-year-old woman who presented with recent-onset exertional dyspnea. Her pacemaker was near end-of-life and reverted to a VVI mode from the preset DDDR mode. Electrocardiography demonstrated retrograde 1:1 ventriculoatrial (VA) conduction and spectral Doppler analysis revealed prominent systolic pulmonary and hepatic vein flow reversals. Symptoms, electrocardiogram (ECG) findings, and the spectral Doppler abnormalities resolved completely following a generator replacement and resumption of DDDR pacing.
