    Minimum information about a cardiac electrophysiology experiment (MICEE): Standardised reporting for model reproducibility‚ interoperability‚ and data sharing by Quinn, T, Granite, S, Allessie, M, Antzelevitch, C, Bollensdorff, C, Bub, G, Burton, R, Cerbaig, E, Chen, P, Delmar, M, DiFrancesco, D, Earm, Y, Efimov, I, Egger, M, Entcheva, E, Fink, M, Fischmeister, R, Franz, M, Garny, A, Giles, W, Hannes, T, Harding, S, Hunter, P, Iribe, G, Jalife, J

    Published 2011
    “…As a step towards establishing this, we present a draft standard, called Minimum Information about a Cardiac Electrophysiology Experiment (MICEE). The ultimate goal is to develop a useful tool for cardiac electrophysiologists which facilitates and improves dissemination of the minimum information necessary for reproduction of cardiac electrophysiology research, allowing for easier comparison and utilisation of findings by others. …”

    Visualization of the SyncAV<sup>®</sup> Algorithm for CRT Optimization by Non-invasive Imaging of Cardiac Electrophysiology: NICE-CRT Trial by Philipp Spitaler, Bernhard Erich Pfeifer, Agnes Mayr, Rudolf Bachler, Valentin Bilgeri, Agne Adukauskaite, Axel Bauer, Markus Stühlinger, Fabian Barbieri, Wolfgang Dichtl

    Published 2023-07-01
    “…There is an unmet need to successfully transform its application into clinical routine. (2) Methods: Non-invasive imaging of cardiac electrophysiology was performed in different device programming settings of the SyncAV<sup>®</sup> algorithm in 14 heart failure patients with left bundle branch block and a PR interval ≤ 250 milliseconds to determine the shortest ventricular activation time. (3) Results: the best offset time (to be manually programmed) permitting automatic dynamic adjustment of the paced atrioventricular interval after every 256 heart beats was found to be 30 and 50 milliseconds, decreasing mean native QRS duration from 181.6 ± 23.9 milliseconds to 130.7 ± 10.0 and 130.1 ± 10.5 milliseconds, respectively (<i>p</i> = 0.01); this was followed by an offset of 40 milliseconds (decreasing QRS duration to 130.1 ± 12.2 milliseconds; <i>p</i> = 0.08). (4) Conclusions: The herein presented NICE-CRT study supports the current recommendation to program an offset of 50 milliseconds as default in patients with left bundle branch block and preserved atrioventricular conduction after implantation of a CRT device capable of SyncAV<sup>®</sup> optimization. …”
