Cover: The temporal evolution of left ventricular shortening measured by magnetic resonance imaging tagging under different pacing protocols: right atrial pacing (right), biventricular pacing (middle), and right ventricular apex pacing (left). Blue, contraction; red, reference state; yellow, stretch. Data are shown for late diastole after tagging (first row), early systole (second row), midsystole (third row), and late systole (last row). These measurements give precise quantification of the regional mechanical consequences of different pacing protocols. From Wyman BT, Hunter WC, Prinzen FW, Faris OP, and McVeigh ER. Effects of single- and biventricular pacing on temporal and spacial dynamics of ventricular contraction. Am J Physiol Heart Circ Physiol 282: H372-H379, 2002.
