The pilot study will be conducted up to three clinical sites in the United States. This study is designed to compare the safety and effectiveness of two types of pacemaker treatments: leadless pacemakers and left bundle area pacing. Patients who's heart rhythm indicate a degree of heart block that slows the heart beat and decreases the amount of blood the heart is pumping to the rest of the body will be identified by physicians to participate. This study seeks to improve our understanding of heart rhythm disorders to allow us to provide the best treatment for our patients."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
