Ocular pneumoplethysmography in cardiac pacing.
Variations in ocular blood flow (OBF) reflect variations in cardiac stroke output very closely. The use of ocular pneumoplethysmography (OPG-Gee) for the measurement of OBF is a simple, noninvasive method of assessing the hemodynamics of ventricular versus atrioventricular sequential pacing.
