Letter to the Editor Temporary third-degree atrioventricular block in a case of apical ballooning syndrome

Apical ballooning is characterized by severe but reversible contractile dysfunction. The causative factor and the pathomechanism remain unknown. Several arrhythmias are reported to occur in apical-ballooning. We present a unique case of a 58-year-old man presenting with apical ballooning complicated by a prolonged third-degree atrioventricular block requiring the implantation of a pacemaker.
