RESUMO
There is increasing evidence that Takotsubo cardiomyopathy behaves more like a highly variable and dangerous syndrome than an isolated cardiomyopathy. In this case report, we describe a case of Takotsubo cardiomyopathy complicated by complete heart block. We discuss the potential mechanisms for its etiology and examine the need for pacemaker placement.

Benzodiazepines are commonly used medications which are clinically useful towards the treatment of alcohol withdrawal, seizures, anxiety disorders, among other indications. Benzodiazepine use is also known to cause the rare phenomenon of paradoxical excitation whose mechanism has many postulated theories. We report this rare presentation of paradoxical excitation with the use of lorazepam in a 50-year-old male being treated for alcohol withdrawal. We also review the underlying pathophysiology, pharmacology, and current literature as it relates to this excitation. An inability to recognize this adverse effect and to appropriately withhold the agent may adversely affect a patient's course of treatment in the inpatient setting.
