Recordings of representative calcium and contractile/twitch transients. Simultaneous recordings of calcium and contractile transients of field stimulated (1 Hz) single cardiomyocytes captured by the IonOptix imaging system: a displacement (Twitch) transients over time of representative single cardiomyocytes from sham, MI + Veh and MI + T3 rats. Vertical scale bar = 0.1 um sarcomere length, horizontal scale bar = 1 s; b Ca2+ transients of single myocytes from each study group showing ratio of fluorescence intensities excited at 340 and 380 nm (Fratio = vertical scale bar); c overlay of twitch and Ca2+ transients from representative cardiomyocytes isolated from MI + Veh and MI + T3 rats
