Why the study?
Does digital arterial pulse volume correlate with stroke volume and PQ interval in patients with complete heart block and artificial pacing?
Does digital arterial pulse volume correlate with stroke volume and PQ interval in patients with complete heart block and artificial pacing?
Plethysmographically recorded digital arterial pulse volume closely correlates with echocardiographic stroke volume, offering a potential non-invasive screening method to identify patients who may benefit from AV synchronous pacing.
No takes yet. Share an insight, caveat, or question.
May support non-invasive AV optimization screening in paced heart block; hypothesis-generating from seven cases and requires prospective validation.
Fagrell et al. (1979) studied this question.
