title: Pulsed Doppler verification of atrial contribution to ventricular filling in sequential pacing.
abstract: We have used pulsed Doppler to ascertain effective atrial contribution to ventricular filling in sequential pacemaker rhythm. The technique is particularly valuable when electrocardiographic evidence of atrial capture is uncertain.
