Each device was immersed in saline with connected leads and programmed to asynchronous or demand pacing with MRI mode ON or OFF. Device interrogation before and after scanning assessed telemetry integrity, parameter retention, and pacing\u2010mode changes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Most CIEDs completed MRI without malfunction and remained telemetric. However, among pacemakers, telemetry failure or parameter reset occurred in 6 non\u2013MRI\u2010conditional and 3 1.5\u2010T MRI\u2010conditional devices, including some devices with MRI mode ON. Reset or telemetry failure was more frequent in devices with low battery status (\u2264\u200930% to ERI) than in those with higher status (6\/11 [55%] vs. 3\/22 [14%],\n                      <jats:italic>p<\/jats:italic>\n                      =\u20090.013). With MRI mode OFF, magnet mode was activated in 11 3T and 7 non\u2013MRI\u2010conditional pacemakers; activation frequency did not differ between asynchronous and demand pacing (16\/31 [52%] vs. 18\/31 [58%],\n                      <jats:italic>p<\/jats:italic>\n                      =\u20090.610). In some pacemakers and ICDs, demand pacing led to atrial mode switch or pacing inhibition, but no reset or telemetry failure occurred in ICDs.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In direct in vitro 3T MRI exposure experiments involving non\u20133T MRI CIEDs, some pacemakers approaching ERI demonstrated an increased risk of telemetry failure or reset, and those with MRI mode turned off showed non\u2010negligible mode switching.
