Or any other prior/planned medical intervention not listed that precludes their
participation in the opinion of the Investigator.

testing:
- Severe aortic stenosis

- Severe proximal three-vessel or left main coronary artery disease without
revascularization

- Unstable angina
- Recent stroke or transient ischemic attack (within the last 6 months)

infection.

implanted device that delivers current in the body.
- Patient meets ACC/AHA/HRS or ESC clinical guideline Class III criteria for an ICD
(e.g., life expectancy of less than 12 months).
- Patient is enrolled or planning to enroll in a concurrent clinical study that may
confound the results of this study, without documented pre-approval from a Medtronic
study manager.
- Patient with any exclusion criteria as required by local law (e.g., age or other).
- Pregnant women or breastfeeding women, or women of child bearing potential and who are
not on a reliable form of birth regulation method or abstinence.
