Why the study?
How can atrial capture be confirmed in patients with committed DVI pacing systems when it is not visible on surface ECG?
How can atrial capture be confirmed in patients with committed DVI pacing systems when it is not visible on surface ECG?
Intentional reduction of ventricular output to subthreshold levels allows rapid bedside confirmation of atrial capture in DVI pacing systems when surface ECG is inconclusive.

May facilitate rapid bedside atrial capture confirmation in DVI systems; hypothesis-generating and requires prospective validation before clinical adoption.
Levine et al. (1983) studied this question.
