We present a unique case of severe HPP associated with both Grave\u2019s thyrotoxicosis and pemphigus vulgaris. The patient developed proximal limb weakness after treatment with rituximab. He then subsequently presented with witnessed ventricular fibrillation arrest. Cardiopulmonary resuscitation was initiated in the field and return of spontaneous circulation was achieved.
