With electrophysiologic and echocardiographic guidance, successful BB capture was achieved on a thin 2.1\u2009mm atrial septum. Pacing significantly shortened P\u2010wave duration (122\u2013&gt;\u200966\u2009ms) and reduced interatrial mechanical delay (53\u2013&gt;\u200940\u2009ms) on speckle\u2010tracking echocardiography.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case demonstrates the acute success of BB pacing in a child.
