Inappropriate timing or duration of the atrioventricular (AV) interval with DDD pacing can lead to hemodynamic compromise. Intraoperative pulmonary venous Doppler interrogation by transesophageal echocardiography can be a valuable tool to assess subtle rhythm abnormalities that may go unnoticed by electrocardiogram and hemodynamic monitoring. We describe a dramatic example of hemodynamic improvement following pacemaker adjustment after pulmonary venous Doppler identified an inappropriately short AV interval.
