Abstract

A 77-year-old woman presented with exertional dyspnea six days after left pectoral pacemaker implantation. Chest radiography at presentation showed that her left diaphragm was elevated when compared to earlier films. A fluoroscopic sniff test confirmed left diaphragmatic paralysis. Thoracic computed tomography did not reveal any major vascular or lung parenchymal injury; however, phrenic nerve injury on direct needle puncture during the original surgery was suspected. The patient's small body size may have increased the risk of this injury. Delayed-onset unilateral diaphragmatic paralysis appears to be a rare complication of cardiac device implantation.
