Recurrent AF occurred in 28% of patients (mean AF burden 0.27), while 773 VT episodes occurred in 15% of patients. Daily intrathoracic impedance, expressed relative to a reference impedance, was analyzed to identify events of impedance decrease and increase. The temporal association between impedance events and tachyarrhythmia burden was quantified using a patient\u2010specific relational strength measure (\n                      <jats:italic>\u03b3<\/jats:italic>\n                      ), which compares post\u2010event and pre\u2010event tachyarrhythmia burden.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      For impedance decreases, event\u2010related\n                      <jats:italic>\u03b3<\/jats:italic>\n                      for AF was higher than control\n                      <jats:italic>\u03b3<\/jats:italic>\n                      computed for randomly placed events (median 0.68 vs. 0.48,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.04).
