Abstract

High degree atrioventricular block (HDAVB) is a rare complication of non-ST-elevation myocardial infarction (NSTEMI) and often requires pacemaker implantation. We describe a case of reversal of HDAVB in a patient with dual atrioventricular node blood supply following coronary revascularization and potential mechanisms of such complications.

Keywords: cardiac conduction disorder; dual atrioventricular nodal supply; high degree av block; nstemi; pacemaker’s implantation; revascularization.
