Atrio-ventricular block and takotsubo syndrome: A review illustrated with two case reports.

Takotsubo syndrome (TS) can be complicated by life-threatening arrhythmias. Data on the association of AV-block, pacemaker implantation, and TS are scarce. We describe two cases of AV-block associated with TS. AV-block persisted despite the recovery of left ventricular dysfunction during follow-up. A review of AV-block and TS association is provided.
