The reversibility of high-grade AV block in non-MI coronary artery disease (CAD), however, is rarely described in the literature. Herein we perform a literature review to assess what is known about the reversibility of high-grade AV block after right coronary artery revascularization in CAD patients who present without an acute MI. To illustrate this phenomenon we describe a case of 2\u2009:\u20091 AV block associated with unstable angina, in which revascularization resulted in immediate and durable restoration of 1\u2009:\u20091 AV conduction, thereby obviating the need for permanent pacemaker implantation. The literature review suggests two possible explanations: a vagally mediated response or a mechanism dependent on conduction system ischemia. Due to the limited understanding of AV block reversibility following revascularization in non-acute MI presentations, it remains difficult to reliably predict which patients presenting with high-grade AV block in the absence of MI may have the potential to avoid permanent pacemaker implantation via coronary revascularization. We thus offer this review as a potential starting point for the approach to such patients.<\/jats:p>","DOI":"10.1155\/2016\/1971803","type":"journal-article","created":{"date-parts":[[2016,1,26]],"date-time":"2016-01-26T21:01:08Z","timestamp":1453842068000},"page":"1-6","source":"Crossref","is-referenced-by-count":10,"title":["Reversibility
