Influence of Aortic Elastic Properties on Pulse Pressure Changes Induced by Rapid Ventricular Pacing.


The mechanism of aortic pulse pressure decline induced by acute rapid ventricular pacing remains incompletely understood. It has been ascribed to changes in stroke volume or aortic compliance. This becomes more complicated by the dependence of aortic compliance on the level of the mean aortic pressure as well as the aortic wall properties. To test the role… (More)
