Outcome Measures
Primary Outcomes (5)
Freedom From MRI Scan-related Complications
Number of subjects who were free from MRI scan-related complications
MRI Visit ,1 Month Post MRI Visit
Change in Right Atrial (RA) Capture Threshold @0.5 Millisecond (ms) From Pre-MRI Scan to 1 Month After MRI Scan
Number of subjects who experienced an increase in RA capture threshold @ 0.5 ms at 1-Month post MRI scan visit ≤ 0.5 Volt (V) compared to pre-MRI scan value collected at MRI scan visit
MRI Visit ,1 Month Post MRI Visit
Change in Right Ventricular (RV) Capture Threshold @0.5ms From Pre-MRI Scan to 1 Month After MRI Scan
Number of subjects who experienced an increase in RV capture threshold @ 0.5 ms at 1-Month post MRI scan visit ≤ 0.5 V compared to pre-MRI scan value collected at MRI scan visit
MRI Visit, 1 Month Post MRI Visit
Change in RA Sensing Amplitude From Pre-MRI Scan to 1 Month After MRI Scan
Number of subjects who experienced a decrease in RA sensing amplitude ≤ 50% and at least 1.5 mV at 1-Month post MRI scan visit compared to pre-MRI scan value collected at MRI scan visit
MRI Visit, 1 Month Post MRI Visit
Change in RV Sensing Amplitude From Pre-MRI Scan to 1 Month After MRI Scan
Number of subjects who experienced a decrease in RV sensing amplitude ≤ 50% and at least 5 mV at 1-Month post MRI scan visit compared to pre-MRI scan value collected at MRI scan visit
MRI Visit, 1 Month Post MRI Visit
