Additional file 4: Video S4 Simultaneous calcium mapping of pig heart epicardium. A juvenile pig heart was imaged during an episode of ventricular tachycardia (cycle length = 150 msec). Circus movement with wave collision can be observed. Transmembrane voltage imaging was performed simultaneously (see Additional file 3: Video S3). The images were box blurred using a 15 × 15 uniform kernel and the length of the heart is approximately 5.0 cm from base to apex. (MP4 16120 kb)
