Differential impact of short periods of rapid atrial pacing on left and right atrial mechanical function
American Journal of Physiology - Heart and Circulatory Physiology, 06/26/2012
Weimar T et al. – Stiffness quantified by the ratio of pressure to volume at end–diastole was increased immediately after RAP only in the RA (P = 0.020), but end–diastolic PVR shifted rightward in both atria (P = 0.011 LA, P = 0.045 RA). These data suggest that even short periods of RAP have a differential impact on RA and LA function, which was sustained for 1 h after conversion to SR.
