Sympathetic crashing acute pulmonary edema following pacemaker insertion.

Key Clinical Message: Sympathetic crashing acute pulmonary edema (SCAPE) complicating pacemaker implantation is a very uncommon and dangerous occurrence. Following pacemaker implantation, patients need stringent monitoring, and compelling evidence about SCAPE treatment is required. Abstract: Sympathetic crashing acute pulmonary edema complicating a pacemaker insertion as the case in our patient is extremely rare. We report a case of 75-year-old man with a complete AV block, which requires urgent pacemaker implantation. Half an hour following the insertion of the pacemaker, an abrupt SCAPE emerged and the patient was incubated immediately.
