Why the study?
Does mild exercise change the relative contribution of early passive and later active phases of transmitral flow to left ventricular filling in normal male subjects?

During mild exercise, active atrial transport progressively increases its contribution to overall transmitral blood flow, primarily due to increased atrial contractility.
No takes yet. Share an insight, caveat, or question.
Active atrial contribution to LV filling rises with mild exercise in healthy men; hypothesis-generating for diastolic assessment in disease.
Channer et al. (1989) studied this question.
