This study intends to enroll patients who meet standard bradycardia or tachycardia indications and have already been implanted with one of the SJM device/lead combinations listed in this protocol. The objective of this study is to confirm the safety and effectiveness of each of the four SJM device/lead combinations in an MRI environment. This clinical investigation is sponsored by St. Jude Medical.', 'detailedDescription': 'This is a prospective, multi-center clinical study designed to confirm the safety and effectiveness of St. Jude Medical low voltage pacemakers, high voltage dual chamber Implantable Cardioverter-Defibrillators (ICD), and Cardiac Resynchronization Therapy Defibrillators (CRT-D) with various leads in an MRI environment.\n\nThe study will enroll subjects across multiple geographies and sites. Sites in geographies where MRI labelling is not yet approved may also be included after appropriate IRB/EC and local regulatory approvals, as applicable, are obtained. A prospective, multi-center study design is chosen for generalizability of study results.\n\nThe clinical study will be conducted in approximately 40 centers worldwide. Approximately 88 subjects total (with a minimum 22 subjects for each of the four device/lead combinations) will be enrolled in this study.\n\nEnrollment in the study is expected to take approximately 6-8 months. Subjects will be followed for 1 month following the MRI scan. The total study duration of the study is expected to be 10 months, depending on the rate of enrollment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Subjects who meet standard bradycardia or tachycardia indications comprise the target population for this study.
