This study is designed to collect high-quality shoulder and intracardiac bi-plane fluoroscopic images during two standard arm motions on patients implanted with a market released SelectSecure 3830 lead for the purposes of developing a fracture reliability model.

Inclusion Criteria:

• Patients who are at least 18 years of age
• Patient has a pacing, ICD or CRT system incorporating at least one SelectSecure 3830 lead in the right atrium or right ventricle
• Patients able and willing to attend imaging session
• Patients able and willing to give informed consent
• Pacing capture threshold and pacing impedance of the lead are within normal range at the time of enrollment
• Patient must be able to accomplish arm flexion and adduction past 90 degrees

Exclusion Criteria:

• Subjects who require a legally authorized representative to obtain consent
• Subjects with exclusion criteria required by local law (e.g. age, breastfeeding)
• Pregnant women, or women of child bearing potential and who are not on a reliable form of birth control
• Subjects that were implanted with a pacing, ICD, CRT device and/or cardiac leads less than three months ago

Subjects of both genders, 18 years of age and older that are currently implanted with at least one SelectSecure 3830 lead, regardless of device type and who meet all inclusion and no exclusion criteria are eligible for the study.
